--- Comment #10 from Ian Lance Taylor <ian at airs dot com> 2012-05-02 04:33:56 UTC --- I don't understand the archive/zip test failure. The files in question are libgo/go/archive/zip/testdata/go-with-datadesc-sig.zip and go-no-datadesc-sig.zip. They exist in the repository. Do they exist in your source tree? The os/user test will fail if run by a user ID for which the libc function getpwuid_r does not return any information.
