I\'ve installed python 2.6 from source, and somehow later mistakenly installed another python 2.6 from a package manager too.
I can\'t find a way to uninstall a pyth
Have you looked into make uninstall I believe this should work for you, assuming you have the python 2.6 source and the make file has uninstall available (it should).
