	The build of math/atlas fails:

Relevant part is the "/lib/libgcc_s.so.1: version GCC_4.6.0 required by
/usr/local/lib/gcc47/libgfortran.so.3 not found", also please note
"-Wl,-rpath=". mat/atlas' Makefile uses EXTRA_FLAGS to pass the rpath to
the linker, as in "EXTRA_FLAGS?=   -Wl,-rpath=${_GCC_RUNTIME}", but
_GCC_RUNTIME is not set:
: cmt at elch:atlas$ make -V _GCC_RUNTIME
: 
: cmt at elch:atlas$

I traced this back to USE_GCC not being set, even though ports commit r344614
http://svnweb.freebsd.org/ports?view=revision&sortby=date&revision=344614
explicitly mentions using "USES=fortran, USE_GCC=yes". Looks like
math/atlas needs the USE_GCC after all.

For lack of time I did not test this with other ports modified in r344614.
