Thanks. I guess I should have included details that I thought
would be of no interest to save people time with replies.

The problem is that on the Mac in question Terminal thinks
python is 2.5 (as does Idle) while when I double-click on a
file in Finder it runs under python 2.3. In particular it
never happens that I'm running an interactive session under
2.3.

(No, I'm not saying that's a good setup - it's a mess. The
other Mac, at the office, is not such a mess, but I never
could get things like Idle to work under the Apple Python...)
