If these versions are no longer supported (for example because we already use library versions that are not supported on those systems), I am inclined to remove these.

Those are good arguments.

I have two follow up questions:
- Should we add a runtime check to prevent users from trying to run a 
newer package on an unsupported OS X version ?
- Should we mention this somewhere on the download page ? Perhaps 
similar to how we handle this with Windows: the download section there 
reads "Windows XP, Vista, 7". Starting with GnuCash 2.6 we may change 
the OS X download section to read "Mac OS X Leopard and up". I'm not 
sure that will improve readability of the download block though.
