You should be using USE_FORTRAN if a Fortran compiler is needed (this
also enforces USE_GCC=4.5), and USE_GCC if only C and/or C++ compilers
are needed.  This should set the right variables in your build
environment (see ports/Mk/bsd.gcc.mk), but a build can still fail if
your local, port, or distribution Makefiles do not respect CC, CXX,
CFLAGS, CXXFLAGS, F77, FC, FFLAGS, or LDFLAGS.  It sounds as if this
is the case, and the Wl,-rpath=... component of the flags added in
bsd.gcc.mk is not being used.
