What steps will reproduce the problem?

1. install pssh 2.2.2 on Ubuntu 10.04.3
LTS 2.6.32-34-server #77-Ubuntu SMP Tue Sep 13 20:54:38 UTC 2011 x86_64 
GNU/Linux

2. a ran ez_setup.py and setup.py

3. pssh gives
Traceback (most recent call last):
  File "/usr/local/bin/pssh", line 24, in <module>
    from psshlib.manager import Manager, FatalError

What is the expected output? What do you see instead?

Do you have another version of pssh installed on your computer by any chance?

Andrew - I am running into this issue too.  I was running pssh 2.1.1 
previously.  What is the best way to uninstall pssh 2.1.1 if the issue is 
having both installed?

I was able to resolve the issue by deleting this file:

/usr/lib/python2.4/site-packages/pssh-2.1.1-py2.4.egg

Hmm. It's disappointing that setuptools installs two files of different 
versions side-by-side. I wonder whether there's a workaround.

djminbild and ryan.brothers, am I correct in assuming that this is a setuptools 
bug rather than a pssh bug? If so, I think this issue should be closed, but I 
feel like you both have more insight about what's going on than I do.

I think I'll go ahead and close this issue for now, but please reopen it if you 
think that there's anything we should do in pssh to address this.  Thanks!

Very helpful.  On OSX, it was under 
/Library/Python/[version-number]/site-packages/pssh-2.1.1-py2.7.egg
