--- Comment #3 from Ian Lance Taylor <ian at airs dot com> --- I can't recreate the problem. It looks like the compilation step in the failing command is reading old versions of the .gox files, versions that use the old pkgpath rather than the new one introduced by the commit. But if you are using a from-scratch build, I don't see where the old pkgpath could be coming from. Have you run `make install` to install an earlier version of the build? Perhaps the compilation command is incorrectly looking at the installed .gox files before looking at the newly built ones.
