Subject: [PATCH] Partial fix to version_ge (greater or equal), was not working
 correctly with eaqual versions, now will do with exact same versions at least
 (yet have to fix case like comparing 1.0 and 1.0.0).

Also refactored a bit osl/llvm/etc. stuff for DEB (so that now all osl-deps are only installed when we do have a valid llvm and want to [try to!] build osl).

And added osl/llvm/etc. code for RPM (osl does not compile under fedora currently, though :/ ).
