Kevin, If you do a "typical" compile of your own Python from source I would install it in /usr/local/ bin and lib. If you download an OSX pre-built Python 2.7.1 (or 3.2) I would let it install itself in /Library/Frameworks/Python.framework/... (See http://python.org/download/releases/2.7.1/)
Then, be really, really sure all 3rd party packages are installed in the appropriate site-packages dir. Each version of Python will likely have its own site-packages and a package installed with one version of Python will most likely *not* be in the correct site-packages dir for your most recent Python. Do not assume you can simply copy a package from one site-packages dir to another as some packages are built for specific versions of Python. And finally, be sure your links, aliases and paths will find the intended version. As to which root dir location is best, it doesn't really matter as long as your links, aliases, and paths can find it. Personally, I have multiple (8) versions installed and use aliases and links to keep things copesthetic. And to avoid issues when installing packages, I use the longer, fully qualified pathnames. I also like reserving /usr/... and /System/Library/Frameworks/Python.framework/Versions/... for the exclusive use by Apple. I do not mess with what I find there. It was "factory installed" and I let only "the factory" modify them. I just make sure my versions are higher on the search list. (Years ago I had BAD EXPERIENCE [on RH 4.x IIRC] when I updated the version of Python I found in /usr/... It seemed safe enough. Let's just say the consequence was *very* painful.) So, armed with this I would first check your links, aliases, and paths. Be sure /usr/local/bin is early in your $PATH. I would carefully inspect for the *correct* packages in the appropriate site-packages dir, re-installing as appropriate. Please know that ElementTree was added to the Python Standard Library as of version 2.5 so you may not want to install another in site-packages. (You may need to tweak your import statements however.)
