- And generally, make things more simple and easy to understand.

After discuss with jhb@ and kib@, here are fixed version of compat[567]x ports
working fine when installed on 8.0.

compat5x:

  Installed under a FreeBSD 6.x or 7.x:
      /usr/local/lib/compat/libpthread.so.1 (file)
    on amd64:
      /usr/local/lib32/compat/libpthread.so.1 (fine)

  Installed under a FreeBSD 8.x:
      /usr/local/lib/compat/libpthread.so.1 -> ./libthr.so.1 (symlink)
    on amd64:
      /usr/local/lib32/compat/libpthread.so.1 -> ./libthr.so.1 (symlink)

- Fix libpthread installation broken on last update
- Use ln -sf instead of -s
- Bump PORTREVISION

Reported by:    erwin

When installing on 8.x (>= 800105), don't install libpthread.so.2 but create a
symlink to /usr/lib/libpthr.so
