While building world with gcc40 I get this error: cpp: in path [/usr/obj/usr/src/ctools_i386_i386]/usr/libexec/gcc40/cpp: No such file or directory Yep, it's true enough. This is because the buildworld target does not yet build gcc40, I assume? I think I'll stick a symlink there pointing to /usr/libexec/gcc40 and see what happens -- today is my day for cheating ;o)
