rpm build from src file
I'm sorry I don't use Fedora so I can't be sure, but I see this has gone unanswered for some time. I do build extensive numbers of RPM's, but for a different distro (PLD).
Your output doesn't say much about what DID get generated. Are you sure a -devel subpackage did not get generated along with the main binary rpm? Did you look at the files inside the src.rpm package and make sure the files you're looking for are in there? Are there any flags for your rpmbuild script to say "include devel files" or something like that?
