It appears that I had python2.4 installed as well as python2.5. Running python, I could not import gtk; but running python2.5, I could.

I uninstalled python2.4, but this doesn't solve the problem. Running pygtkeditor now gives me a message, "...python: not found."

I tried uninstalling and reinstalling pygtksourceview and pygtkeditor, but that didn't help.

Do I have to reinstall python? And reinstall all applications that depend on it?

Thanks.
