It shows, that system /usr/lib/libstdc++.so.6 depends on gcc44's libgcc_s.so and it is completely wrong!

It is why I want to determine MINIMAL set of ports, which are REALLY depend on gcc4 For example, x264 DEPENDS on gcc, (has USE_GCC=3D4.4+ in Makefile), but no x264 files are linked with libgcc_s.so or other libraries from gcc44. It seems, that we need separate USE_GCC_BUILD and USE_GCC_RUN, as with PERL or PYTHON. --=20 // Black Lion AKA Lev Serebryakov <lev@FreeBSD.org>
