great work! When using RHEL/CENTOS python > 2.4 remember to use also the yum-priorities package in order to avoid python libraries overwritings which will break the system. You can follow this guide http://www.grenadepod.com/2009/12/21/sorting-out-yum-repositories-on-centos-5-4/ Also, if you really don't wanna mess up your python2.4 installation and you want to try out different libraries with different configurations on 2.6 I find "virutalenv" very comfortable used in conjunction with pip or easy_install. http://pypi.python.org/pypi/virtualenv By the way, I'm splitting in two the CASPER control stuff as bee_xps on CENTOS and control/acquisition/postelaboration on UBUNTU which makes things really easier.
