You didn't look:
* Mon Feb 07 2011 Fedora Release Engineering
<rel-eng@lists.fedoraproject.org> - 5:6.1.5-18
- Rebuilt for https://fedoraproject.org/wiki/Fedora_15_Mass_Rebuild

Standard practice when branching a release, to ensure packages that may
not have been re-built don't have broken dependencies.

If you add this patch to Fedora am-utils it then works?

If that's not the case then there is more work to do!
