The cmake files for building python are now in a cvs repository:
http://www.cmake.org/cgi-bin/viewcvs.cgi/Utilities/CMakeBuildForPython/?root=ParaView3

This is inside the ParaView3 repository:
http://www.paraview.org/New/download.html

I used them today to build Python from svn trunk.

I'll add some documentation how to use them, how to get them and what works 
and what doesn't work tomorrow.
