That's not quite how Macports works. Macports is a package manager.
Each package has a port file with (among other things)
1) A location to download the source tarball
2) A list of patches to apply
3) A list of dependencies
4) Sets of config arguments and build scripts for different variants

Richard, if something goes wrong with Macports, nuking /opt/local does
a pretty good job of cleaning it up. And even if you don't want to use
Macports, you can still grab their patches. They're all here:
http://trac.macports.org/browser/trunk/dports/lang/python32. You can
dig through the portfile to see what patches and config flags they're
using to build it.
