I had to add the following changes to lang/gcc4 in order to get it building:

lang/gcc4/Makefile had to be modified to add support for math/mpfr package,
otherwise Fortran compiler cannot be build:

.if !empty(BUILD_F77:M[Yy][Ee][Ss])
.include "../../devel/gmp/buildlink3.mk"
.include "../../math/mpfr/buildlink3.mk" 
CONFIGURE_ARGS+=        --with-gmp=${BUILDLINK_PREFIX.gmp}
CONFIGURE_ARGS+=        --with-mpfr=${BUILDLINK_PREFIX.mpfr}
USE_TOOLS+=             chmod
MAKE_ENV+=              ac_cv_path_ac_cv_prog_chmod="${TOOLS_CHMOD}"
.endif


Also I had to add the following patches, which are Solaris specific and
are described at http://gcc.gnu.org/gcc-4.0/changes.html#4.0.2
