[Pythonmac-SIG] Future 64-bit installers

We had a short discussion on the 2.7-macosx10.5 installer for python 2.7 at the europython language summit due to the unfortunate problems with IDLE and Tkinter in that installer: tkinter doesn't work in 64-bit due to being linked with Tk 8.4 and for some reason IDLE.app doesn't work either (even though that worked earlier in the develpment process).

The consensus at the summit was to replace the macosx10.5 installer (ppc, x86, x86_64) by a macosx10.6 (x86, x86_64) installer for future releases. That enables linking with Tk 8.5 and that would solve a number of issues other than being available in 64-bit code.

Users of OSX 10.5 (or earlier) can still use the macosx10.3 installer, that would stay the same. The only difference for OSX 10.5 users is that they cannot use 64-bit code without building their own binaries.

The alternative to raising the OSX requirement is to ship Tk 8.5 in the installer and that would grow the installer, and would increase my load.


P.S. It should be possible to use the future macosx10.6 installer to install on 10.5 as well if you install Tk 8.5 yourself, but this won't be prominently advertised.
