With Phillips's help I figured out the problem:
scott@scott:~/scott/python/wxoptparse$ runWx
Traceback (most recent call last):
  File "/usr/bin/runWx", line 4, in ?
    pkg_resources.run_script('wxOptParse==0.1.2', 'runWx')
  File "/usr/lib/python2.4/site-packages/setuptools-0.6a1c2-py2.4.egg/pkg_resources.py", line 407, in run_script
    self.require(requires)[0].run_script(script_name, ns)
  File "/usr/lib/python2.4/site-packages/setuptools-0.6a1c2-py2.4.egg/pkg_resources.py", line 914, in run_script
    raise ResolutionError("No script named %r" % script_name)
pkg_resources.ResolutionError: No script named 'runWx'
scott@scott:~/scott/python/wxoptparse$ cd ..
scott@scott:~/scott/python$ runWx
usage: wxoptparse.py <programtorun>

Basically, I was testing within my source directory and it was getting confused when it saw a folder called wxoptparse.  The error was not very helpful in this case.

Here's what I did.  I'm running on cygwin, not Linux, but it seems like it
should be similar.  In any case, I'm not getting the problem.  I wonder if
perhaps you have a PYTHONPATH set up that is somehow finding the wrong
version of your egg?  (i.e., a version that doesn't have the script).  Just
a thought.
