Either run python-updater _before_ you uninstall your old python or use the -o command switch to set your old python version. There's no sane way to determine your old python version after you uninstall it. The most logical way is to check old site-packages/ directories for leftovers but that will fail if you only have packages that didn't install anything under site-packages/ but _still_ need to be rebuilt. -o is your friend, this is exactly the reason why it's there.
I understand what the problems is. What I miss is the error message "Couldn't determine any previous Python version(s)". Shouldn't python-updater-0.5 print this error message in any case?
See my last comment.
Yes, the fact that python-updater says nothing is confusing. A user might conclude that there's nothing to do. It would be nice if it instead output a message like "Only one Python version installed, use the -o option to indicate old version number." Okay, *after* the first time you've inadvertently deleted an old python version before running python-updater, and trawling the web and finding out that you need to use python-updater anyway, you will know what to do. But for first-time python-updater users, something like this would be a simple helpful message pointing the user in the right direction.
This should be fixed in svn¹ and will be released with the new version soon: alip@trippin> eselect python list Available python interpreters: [1] python2.6 * alip@trippin> python-updater * Couldn't determine any previous Python version(s). * Use -o OLD_PYTHON_VERSION to specify your old python version. ¹: http://overlays.gentoo.org/proj/python/changeset/106
Version 0.6 should fix this, thanks for reporting.
