Gfan is a software package for computing Groebner fans and tropical
varieties.
This port provides only the static library libgfan.a. You can get the
rest of the software package from math/gfan.
Remove WWW entries moved into port Makefiles
Commit b7f05445c00f has added WWW entries to port Makefiles based on
WWW: lines in pkg-descr files.
This commit removes the WWW: lines of moved-over URLs from these
pkg-descr files.

Add WWW entries to port Makefiles
It has been common practice to have one or more URLs at the end of the
ports' pkg-descr files, one per line and prefixed with "WWW:". These
URLs should point at a project website or other relevant resources.
Access to these URLs required processing of the pkg-descr files, and
they have often become stale over time. If more than one such URL was
present in a pkg-descr file, only the first one was tarnsfered into
the port INDEX, but for many ports only the last line did contain the
port specific URL to further information.
There have been several proposals to make a project URL available as
a macro in the ports' Makefiles, over time.

Bump PORTREVISION for ports depending on the canonical version of GCC
as defined in Mk/bsd.default-versions.mk which has moved from GCC 8.3
to GCC 9.1 under most circumstances now after revision 507371.
This includes ports
- with USE_GCC=yes or USE_GCC=any,
- with USES=fortran,
- using Mk/bsd.octave.mk which in turn features USES=fortran, and
- with USES=compiler specifying openmp, nestedfct, c11, c++0x, c++11-lang,
c++11-lib, c++14-lang, c++17-lang, or gcc-c++11-lib
plus, everything INDEX-11 shows with a dependency on lang/gcc9 now.

Add USES=compiler:c++11-lang to fix build on GCC-based architectures.
While here, add USES=localbase to simplify.

Gfan is a software package for computing Groebner fans and tropical
varieties. These are polyhedral fans associated to polynomial ideals.
The maximal cones of a Groebner fan are in bijection with the marked
reduced Groebner bases of its defining ideal. The software computes
all marked reduced Groebner bases of an ideal. Their union is a
universal Greobner basis. The tropical variety of a polynomial ideal
is a certain subcomplex of the Groebner fan. Gfan contains algorithms
for computing this complex for general ideals and specialized
algorithms for tropical curves, tropical hypersurfaces and tropical
varieties of prime ideals. In addition to the above core functions
the package contains many tools which are useful in the study of
Groebner bases, initial ideals and tropical geometry.
