Description of problem:
It looks like this is a side effect of the change with unversioned doc dirs and the upstream makefile following this convention but RHEL6 rpm macros still expecting it to be versioned (as well as older Fedora releases)

Version-Release number of selected component (if applicable):
appliance-tools-007.4-1

I put together a small patch and built against EPEL6 and Fedora Rawhide to verify it works. My spec file and SRPMs are here:
SPEC URL: http://maxamillion.fedorapeople.org/appliance-tools.spec
SRPM URL: http://maxamillion.fedorapeople.org/appliance-tools-007.4-2.el6.src.rpm


Also, here's the patch in case that''s useful:
