In true Linux fashion, there's more than one way to do it:

1. Maintain your own python installation, as you said.

2. Use "easy_install" or "pip" or "setup.py" to install the module
into the eups python dir.  Note that the module is then part of that
eups python module (so if you upgrade python, or you haven't "setup
python", then it's not available).

3. Use "easy_install" or "pip" or "setup.py" to install module into
some other dir on your PYTHONPATH.  Then it's always available no
matter what python you're using, but you may have trouble if your
system python and eups python aren't the same minor version (e.g., 2.6
vs 2.7).

4. Manage the module as an eups package.  Install it into the proper
place in the eups tree and give it a eups table file.  This allows
versioning (unlike any of the above methods, unless you're using
virtualenv or similar), and access for multiple people.
