I misled you the first time, but have since taken another look
at the installation to see how it works. In order to import
anything from a package (roughly, a set of .py files that includes an
__init__.py file), you need to put those files in a directory
which is named for the package (e.g. pysnmp in this case) _and_
which is available in sys.path. (Do "import sys" and "sys.path"
to see the list. You probably have lib/site-packages in that
list, so just put all the PySNMP files under it in a folder called
> - Do I need to explicitly mention in my script where pySNMP is
Not if it's in a folder called pysnmp that is itself in one of the
sys.path folders, or under the current folder.

Distutils is included in Python so you probably didn't need to do
that, and maybe shouldn't have. I'm not sure whether that will have
broken the standard distutils. It's repairable if it did. On my
Python 2.2.1 setup here, the standard distutils is v1.0.3.

Now that's a different problem. You need python.exe to be findable
from the DOS PATH. The simplest approach might be to check the FAQ
entry at http://www.python.org/cgi-bin/faqw.py?req=show&file=faq08.018.htp
As a test of the pysnmp installation, without having to change PATH
at all, change to the Python directory ("cd \python" or whatever)
and run the interactive interpreter ("python") and just type
"import pysnmp" to see if it works.

Should all be no problem, although I suspect instructions in that
FAQ entry may be a little light on XP advice. Let us know if you
see any area that could be improved so others can benefit from this
