Remove unmaintained lang/drscheme port, which is superceded by
lang/plt-scheme. According to pointyhat lang/drscheme it has been
broken since 2007/06.

-Repocopy devel/libtool15 -> libtool22 and libltdl15 -> libltdl22.
-Update libtool and libltdl to 2.2.6a.
-Remove devel/libtool15 and devel/libltdl15.
-Fix ports build with libtool22/libltdl22.
-Bump ports that depend on libltdl22 due to shared library version change.
-Explain what to do update in the UPDATING.

It has been tested with GNOME2, XFCE4, KDE3, KDE4 and other many wm/desktop
and applications in the runtime.

- update to jpeg7
Tested by:      pav on pointyhat

- Update X.org ports to 7.4+ (few ports are more recent than the katamari).
- Bump PORTREVISION for all ports depending on libglut since the shlib
version number went from 4 to 3.
- Bump PORTREVISION for all ports depending on libXaw as libXaw.so.8 isn't
installed anymore.
- Couple of ports fixes (mostly missing xorg components added to USE_XORG).

- Mark IGNORED on pointyhat - receives signal 10 during build on pointyhat, but
  builds on my regular workstation

- Fix segfaults, unbreak
- Add missed xorg dependency

BROKEN: Segfault during build

Upgrade to v370.  The port now unconditionally depends on Cairo
graphics.  Additional upstream changes include:
 - The conservative garbage collector (CGC) has been replaced with a
   precise garbage collector (3m) in the standard build.  For most
   users, this change simply amounts to "better performance in space
   and time".  Use the port knob 'CGC' to build DrScheme with
   the conservative garbage collector.
 - Unit-based servlets are no longer supported in the web server.
   Use module-based servlets, instead.
 - A new `(lib "unit.ss")' library replaces the old one and provides
   a simpler and more flexible syntax.
 - The HtDP "world.ss" and "image.ss" teachpacks have been revised,
   including support for the creation of animated GIFs and DrScheme's
   teachpack GUI now works only with the HtDP languages.  In other
   languages, use `require' to access teachpacks.

- Welcome X.org 7.2 \o/.
- Set X11BASE to ${LOCALBASE} for recent ${OSVERSION}.
- Bump PORTREVISION for ports intalling files in ${X11BASE}.

Upgrade to v360.  Upstream changes include:
 - A new macro stepper that traces through macro expansion
   step by step.
 - A new "Lazy Scheme" language level.
 - New support for prompts and composable continuations.
 - Regexp support now includes the usual collection of
   "Perl-compatible" features.
 - Compiler improvements and bug fixes.

Fix compilation on FreeBSD 5.X.

PR:             ports/105381
Submitted by:   Thorolf (thorolf at grid einherjar de)

- Upgrade to v352.  This is a bug-fix release.
- Tweak the port's build to detect and use libpng and
  libjpeg present in $LOCALBASE.
- Build this port for the amd64 architecture in addition to i386.

- Bring down the parts of upstream change SVN#4389 that make
  .zo file generation more deterministic.  Package building
  should work reliably now, so unbreak the port.
- Explicitly depend on -lXft.
- Change the build to always use the libjpeg and libpng
  libraries bundled with the source package.

BROKEN: Does not compile

Update to v351.

Upstream changes include:
 - bug-fixes,
 - improved 3m performance,
 - HtDC libraries have been reorganized into four packages,
 - improvements to the 'Debug' button, including persistent
   breakpoints,
 - expressiveness improvements and a 2x performance boost
   for tight loops that do a lot of contract checking.

This port no longer requires `gmake`.

Upgrade to v350.

Major changes include:
 - A new JIT compiler for mzscheme.
 - The installed port uses a hier(7)-compatible directory
   structure under ${PREFIX}.
 - ProfessorJ includes a unit-testing mechanism.
 - The default exception handler in mzscheme now shows
   stack-trace information.

The port now offers a new option 'MMM' that builds DrScheme with
the experimental 3M garbage collector.

Upgrade to v301 --- bug fixes and changes to the demos.

- Upgrade to v300.  This DrScheme release offers Unicode support,
  a foreign function interface, anti-aliased text, and many other
  extensions and improvements.

- Add a port knob 'CAIRO' to conditionally allow compilation with
  the Cairo graphics library.

Add SA256 checksums.

X11BASE and portlint cleanups.

Use the virtual category "scheme" (part ii)

        Add the virtual category "scheme" to the maintained ports
        (except sxm). I guess no maintainer would deny this trivial
        change.

Move downloaded distfile to a directory numbered by ${PORTVERSION} to

being picked up during the "fetch" phase.
