The fd.o version comparison is rather odd indeed, and unless someone really wants our pkg-config to support versions like '1:2/3alpha' I think we will stick to a clearly documented (I'm working on that) comparison algorithm that is strict and won't allow junk like '2.1.3~rc5' from ftgl. That was actually the first version I encountered in our tree that uses such a twisted scheme. So, we're probably not going the same way fd.o went with comparison schemas and I don't think many upstream projects favor it either. -- Cheers, Jasper "Capable, generous men do not create victims, they nurture them."
