Before searching manually, we should attempt to use whatever is set in the environment.

These are both valid on Fedora 15, iirc before distributions started shipping Python 3 they were less common though...
both of them are ok for archlinux, but I don't know which is ok for other distributions, maybe both are not.
maybe we can make a shell script to detect the python version, and make a symbollink to the right one in some directory, and add the directory into env var "PATH".
Patches welcome :-)
I looked at it briefly and the work would require more time than I have spare right now just to ensure it worked on all required distributions.
If you'd like to work on a patch I'd be happy to help test and review.
