right -- I'm not sure if it's useful, though, I don't' think there is a 
64 bit interpreter, for instance. But maybe that was the one delivered 
with 10.5. But I'm not the one to ask -- I don't have 10.6, I'm still on 
an old PPC running 10.4.

Yes, the whole thing is a nightmare, really. 32bit ppc+i386 was bad 
enough -- with four now, it's really a mess.

You're right -- still strictly Carbon, and therefor strictly 32 bit.

well, /opt has kind of been co-opted by macports.

wxPython gets put entirely into:


which isn't bad.

OK -- what about simply punting and doing two builds: one 32 bit, and 
one 64 bit. I wonder if we need 64bit PPC at all? I know I'm running 64 
bit hardware, but never ran a 64 bit OS on it -- I wonder if anyone is?

What machines/OS versions are available for building Mac installer with? 
I could do 10.4, 32 bit, ppc+intel.

I'll post on the pythonmac list to see what folks there think.
