Mock can't build x86_64 packages

[Clodoaldo Neto]

Trying to build rpm packages with mock in F11 i386:

I can build i386 packages but not x86_64 as I get this:

 You could try using --skip-broken to work around the problem
 You could try running: package-cleanup --problems
                        package-cleanup --dupes
                        rpm -Va --nofiles --nodigest
The program package-cleanup is found in the yum-utils package.
