You can create stages that does not contain sys-devel/gcc in the future.

Created attachment 448824 [details, diff] sample patch for catalyst/targets/stage2/stage2-chroot.sh You can make stages without gcc NOW. Several steps are required. echo '-*sys-devel/gcc' >> /usr/portage/profiles/arch/amd64-fbsd/clang/packages gsed -i '/sys-devel\/gcc/d' /usr/portage/profiles/default/bsd/fbsd/packages.build Apply attachment patch to catalyst. And apply attachment patch to sys-auth/pambase... In the future, I think that good solution as virtual/system-compiler than this bad way.
*-fbsd is gone.
