Running Python program gives undefined symbol

[jeffbarish]

And here's another problem with the Python in Edgy: when I attempt to run Python programs that used to work, I often get the message:

undefined symbol: PyFPE_jbuf

This error message appears, for example, when I try to run pydoc. Here's the traceback:

Traceback (most recent call last):

Mystery solved: After installing Ubuntu, I copied over the old /usr/local/bin. It contained an old Python which was getting picked up before the correct one in /usr/bin.
