Re: [Pyobjc-dev] pyobjc 2.0 on Leopard with MacPython?

Ronald,

Thanks for the clarification! In the long run, it would definitely be
worth the effort to get pyobjc2 working on the 10.4u.sdk. On a side
note, would you be willing to share what features are present in the
system python that aren't available in the MacPython build (for 10.5)?
