Hi there,
This message is a continuation of a previous thread I started regarding my
difficulties in getting PythonImport to work. (thread text is attached).
Moved my dev environment to Linux. Still having failure of PythonImport
(see snippet below for error). Simply put ChrisTest.py in the site-packages
directory.
[Mon Apr 9 17:10:38 2001] [notice] Apache/1.3.19 (Unix) mod_python/2.7.2
Python/2.0.42-S1.2.4 configured -- resuming normal operations

ChrisTest
Using the following directive
PythonImport ChrisTest
Looking through mod_python.c, it's apparently failing on trying to import
the module (duh), but I haven't jumped in deeper. Any help/ideas would be
greatly appreciated... Thanks.

Try the mod_python 2.7.2 DLL and see if the problems persist
