I just tested the Fedora 18 published version. It certainly compiles
successfully on SL 6, although I don't have a good test suite to work
with it. Simply get the Fedora RPM, and run "rpmbuild -ba
laback-[version].src.rpm". You will need to provide build
dependencies: if possible, I also highly recommend using "mock" to
build RPM's like this, so you get them built in a clean environment.
