Python 2 6

We have a shell script that you can just source allowing you to use the default Python26 coming with CMSSW5xy

So after copying it just run:

source ./move_to_python26.sh

Then you should have:

[foobar@m2 ~]$ which python
/sandbox/cmss/slc5_amd64_gcc434/cms/cmssw-patch/CMSSW_5_0_1_patch3/external/slc5_amd64_gcc434/bin/python
[foobar@m2 ~]$ python -V
Python 2.6.4
