[Dev] experimenting with python 2.4

[Andi Vajda]

If you would like to experiment running Chandler with python 2.4, here is what 
you need to do. It involves doing a full Chandler build from scratch.

Note: the Chandler build is still configured to build with python 2.3.3 by
       default.

   - cvs update external internal
   - cd external
   - edit Makefile.inc and change PYTHON_VER to be set to 2.4
   - edit python/Makefile and change VERSION to be 2.4
   - do a thorough cleaning of your release and debug directories by removing
     them: rm -rf release, etc....
   - do the same for your Chandler's release and debug dirs
   - do a full build in external and internal and install the binaries:
     cd external
     make
     cd ../internal
     make
     cd ../external
     make binaries install
     cd ../internal
     make install
   - as a precaution, remove the old .pyc and .pyo files in Chandler
     cd chandler
     find . -name '*.py?' | xargs rm
   - on Mac OS X only: export PYTHON_VER=2.4
   - run Chandler
     cd chandler
     release/RunChandler -stderr -create
