[Pythonmac-SIG] Having trouble building Python w/ Tcl/Tk on my new Macbook Pro

[skip at pobox.com]

I finally put my PowerBook G4 out to pasture and bought a MacBook Pro.  I
used SetupAssistant to transfer data from the old box to the new one.

I'm having trouble building any version of _tkinter (from svn 2.5, trunk
(2.6) or py3k) on my new box.  Today I decided to debug the problem a bit.
I'm getting this warning when linking _tkinter.so:

    ld: warning in /Library/Frameworks//Tcl.framework/Tcl, file is not of required architecture
    ld: warning in /Library/Frameworks//Tk.framework/Tk, file is not of required architecture

which suggests to me that those versions of Tcl and Tk are probably PPC
only.  (I suspect old AquaTk frameworks copied over by SetupAssistant.)
Looking in /Library/Frameworks I see

There are a number of frameworks there which look suspiciously old.  How can
I tell which are PPC and which are Intel?  Is it okay to just remove the Tcl
& Tk frameworks?  (Renaming them caused the link to succeed.)  I noticed
much more recent versions in /System/Library/Frameworks.

Thanks,
