I also had some problems with easy_install. Specifically, I was playing around with qt4 -- trying to get a qt4 backend for matplotlib, trying to get a qt4 backend for opencv, etc. I had problems installing the qt4 python bindings through easy_install, and so I went back to macports.

By good luck, I mean that the entire suite of rxtools (at least all those mentioned in tutorials) work, which is a first for me.
