Update "pkg_install" to version 20120128:
- pkg_install 20120128:
- Explicitly stat(2) if mkdir failed. errno detection doesn't work e.g.
on Solaris.
- Provide a stable order for package names that only differe in the base
name, not the version number.
- pkg_install 20110805:
- Fix for pkg_delete on NFS from Anthony Mallet.
