The module is named MMTK, not mmtk. Python module names are case  

And then, as Peter already pointed out, Python C modules (MMTK has a  
few of those) compiled for Python 2.3 don't work with 2.4. So you need  
to install MMTK (and also NumPy and Scientific Python) under Python

That's a good idea as well. Note that there is a small problem with  
having multiple Python installations on one system: there is only one  
PYTHONPATH. Both Python 2.3 and 2.4 will look for modules in the same  
place, but only one of them can find correct C modules there.

One workaround is to write a wrapper script that sets PYTHONPATH for a  
specific version and then executes it.
