It's clear from the traceback above that the standard library random.py 
file is not being imported.  That file is here:

/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/random.py

There is nothing like "import rand # handy random-number functions" in 
it.  And the path reported is "random.py", not 
"/Library/Frameworks.../random.py".  IDLE.app changes its working 
directory to the Documents directory in your home directory so that path 
is what one would expect for a file from there.

The most likely culprit is in your ~/Documents folder.  That would 
explain why all versions of IDLE are being affected.

A Google seach for that string turns up this:
<http://www.strout.net/python/warmer.py>
Does that ring any bells for you?

How about a Spotlight search for "handy random-number functions"?  

Something else to check is environment variable settings.  What does 
this produce in a terminal shell?:
   env | grep PYTHON

And try temporarily disabling the IDLE preferences files:
   mv ~/.idlerc ~/.idlerc-disabled

If you are seeing the same behavior with multiple versions of IDLE, make 
sure the Console output for each is similar to that above.
