4Suite

I ran "sudo python setup.py install", and got the following error:

Traceback (most recent call last):
File "setup.py", line 136, in <module>

File "/usr/lib/python2.5/distutils/core.py", line 112, in setup

ValueError: empty package restriction


This error message doesn't give me much information on what went wrong.
Does anyone know what is wrong. I'm running Ubuntu and Python 2.5.2.

Thanks!
