[Distutils] Trouble installing Myghty with --prefix

Thanks, but that's not what I'm after.  On my CentOS 4 server, Python 2.3.x
is installed with /usr as the prefix (that is, I use the CentOS-provided
version of Python).  I install all third-party packages (including my own
code) with a prefix of /usr/local/mojam so I can a) avoid polluting the base
package and b) install things without becoming root.  Accordingly, I dump a
mojam.pth file in the system site-packages directory which contains this one
line:

    /usr/local/mojam/lib/python2.3/site-packages

That is my only pollution of the default Python installation.  I'd like to
keep it that way.  Can setuptools (be made to) do the job?

Thx,
