Not necessarily. It would be nice if every package used the same layout 
of the version string (maybe the scheme used by python itself), but the 
Linux package manager seem to have an pretty accurate heuristic for 
comparing versions. Borrowing that heuristic would also work.

BTW. I just noted that PackMan (the GUI) doesn't have an 'uninstall' 
option. That makes it harder to throw away packages that are not really 
needed.
