Description of problem: This library needs to be rebuilt. Without rebuilding it linking ocaml programs against this library cause ld to fail with an error. I encountered this while trying to build the why3 package. Downloading the SRPM and building it and installing it allowed my build to succeed.
Be helpful if you could say what the error was. I just compiled a lablgtk program on F16 and it compiled and linked fine, so I'm doubtful that rebuilding lablgtk was more than just a coincidence. Nevertheless I've rebuilt it for you: http://koji.fedoraproject.org/koji/taskinfo?taskID=3991877
