When I open Terminal I see the following:

Everything seems to work but this is ugly and maybe warns of future trouble. I've installed Python 2.7 on this machine, then removed it to a virtualenv to restore 2.6 as the system default.

Any thoughts on how I can debug this?

EDIT:

My .profile has a call to virtualenvwrapper.sh -- which, as I look it, is located under .../Versions/2.7 of Python. So maybe I should look for the problem there?

Maybe I'm missing something here, but why is python loading anything when you start Terminal.app? Do you have something specific in your .bashrc or .profile that executes some python code? –  cm2 Feb 10 '12 at 16:53
    
Yeah, virtualenvwrapper.sh, see my edit. –  chernevik Feb 10 '12 at 18:06
    
Yeah, that's it -- pointing .profile to /Versions/Current/bin/virtualenvwrapper.sh makes the cruft go away. Phrase as an answer and I'll choose it. –  chernevik Feb 10 '12 at 18:11
    
Looks like you answered it yourself. Its ok to accept your own answer. –  cm2 Feb 10 '12 at 21:36

From comment:

Check your .bashrc or .profile for Python specific code -- if you find something there make sure it is pointing to the correct version, be it .../Versions/Current/..., .../Versions/2.7/..., or whatever.

The issue is correct but the solution is not necessarily - your current python might not be the one you want if you have multiple pythons –  Mark Jul 22 at 15:23
    
@Mark: How's this? –  Ethan Furman Jul 22 at 17:55
