It's not confusing, it's right. gcc is not able to compile indeed. > I'm happy to leave the problem of setting -rpath to pkgsrc maintainers > as I just want to do a full gcc bootstrap to test another libgcc patch. I think it is user error. If your libraries are not in the right place, either you rely on .la files and force everyone to use libtool (not a good idea), or you put the paths in LD_LIBRARY_PATH/LD_RUN_PATH, or you add flags manually to the configure line.
