It may be sometimes helpful to get more explained messages from rpmlint, if you start it over the fedpkg lint command. Therefore I have implemented a -i/--info switch for fedpkg lint
You may find the implementation at commit cf2f964727bce92ca54dc4bc6bf53a039c0af563 at git://fedorapeople.org/~s4504kr/public_git/fedora-packager.git
Hrm, I don't see that commit, nor anything from you in that repo that has to do with 'lint'.
I responded to an email that had a patch for this. It needs just a slight bit more work.
