ularn rebuild failure

[Wart]

This one has me stumped:

http://koji.fedoraproject.org/koji/getfile?taskID=1180936&name=build.log

I get the same error when I build locally with mock.  However, if I go
into the buildroot, I can see that the config.h.SH file is there.
Inserting 'ls -l config.h.SH' into %build also shows that the file is
there.  If I chroot into the mock buildroot and run '. config.h.SH', it
works.

This same package built fine for F10.  Any ideas what's causing this odd
behavior?
