"MacOS X: Enable 4-way universal builds ..."
This revision made the following change to Mac/Makefile.in:

The last hunk (part of the "installmacsubtree" target) and a bit of the
preceding hunk uses `arch` with arguments:

---------------------------------
That form of calling `arch` is only supported on Mac OS X 10.5
(Leopard), I believe.

----------------------------------
Here is the current man page for arch (I had to look to try to see what
Ronald was trying to do with the Makefile change) :)
http://developer.apple.com/documentation/Darwin/Reference/ManPages/man1/arch.1.html
I don't fully understand why the "arch -ppc -i386" is necessary for
"$(BUILDPYTHON)".
I'm not sure what the easiest solution to this would be... or if
supporting "make frameworkinstallframework" (which eventually calls this
target) on Mac OS X <10.5 is considered important enough.
Perhaps a new 
 RUNARCH=@RUNARCH@
could be added to Mac/Makefile.in with the associated configure support
to have that be blank unless `--with-universal-archs=all` was specified?
