>Description:
USE_GCC is a nice idea, but it is too static.
For example, a port which has USE_GCC=3.2 but can live with gcc 3.3
has to recompile the whole compiler kit anyway.
>How-To-Repeat:
>Fix:
Remove everything with regarding to USE_GCC in bsd.port.mk.
Add these lines:
.if defined(USE_GCC)
.include "${PORTSDIR}/Mk/bsd.gcc.mk"
.endif
And add this file to ports/Mk/bsd.gcc.mk

# bsd.gcc.mk - Support for smarter USE_GCC usage.
#
# Created by: Edwin Groothuis <edwin@freebsd.org>
#
# For port developers:
# If your port needs a specific version of GCC, you can easily specify
# that with the "USE_GCC=" statement. If you need a certain minimal version,
# but don't care if about the upperversion, just the + sign behind
# the version.
#
# For example:
# USE_GCC= 3.3 # port requires gcc 3.3 to build with.
# USE_GCC= 3.1+ # port requires gcc 3.1 or later to build with.
#
# If you are wondering what your port exactly does, use "make test-gcc"
# to see some debugging.
