What 3rd party modules are you planning to use?

You won't be able to use them until their developers release
Python 3000 versions.

In my research, I heavily depend on the gmpy module for
fast, number theoretic functions. Last time I checked,
it was only available for v2.5.

So, I could install v2.6 or v3.0, but I wouldn't be able
to run any of my programs, so what would be the point?
