Ok, I give up. I'm using setuptools==0.5a13 and have the following problem.
I'm trying (under Ubuntu Linux) to have my easy_install.py install a script to run my utility. However, it's unable to find the utility and I don't know why.
The latest incarnation I changed the name of the script to runWx. Here's what happends when I run it:
$ 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-0.5a13-py2.4.egg/pkg_resources.py", line 111, in run_script
    require(dist_spec)[0].metadata.run_script(script_name, ns)
  File "/usr/lib/python2.4/site-packages/setuptools-0.5a13-py2.4.egg/pkg_resources.py", line 627, in run_script
    raise ResolutionError("No script named %r" % script_name)
pkg_resources.ResolutionError: No script named 'runWx'

it can't find runWx, ok, why not?

here's the egg list:
$ unzip -l dist/wxOptParse-0.1.2-py2.4.egg

Here's the contents of /usr/bin/wxRun which appears to have been created:
$ cat /usr/bin/runWx

import pkg_resources
pkg_resources.run_script('wxOptParse==0.1.2', 'runWx')

My setup.py file:

    description="wxOptParse: run the command line options from a dialog box.",
wxOptParse is a Python program that brings up a graphical representation of the options
that another python program has for the command line, via the optparse module.

What this means is that if if you have a program that uses optparse you can click on checkboxes,
edit boxes, combo boxes, etc. instead of using the command line.

Any help would be appreciated, this program won't be very useful if it's can't be run from the command line.
