Best way to acces shelves from embedded python

[Craig Rendon]

Dear Python  People,

Question:

My question is:  what is the best way to access shelves from embedded
python?

What I've done so far:

I am trying to write a serial driver daemon that loads a simple database of
comm port parms from a Python shelve.  Using the "simple strings" strategy,
I get an ImportError.  The error (see traceback, .c and .py modules below)
is due to an undefined symbol in struct.so.  If I use the "calling Python
Objects in modules" strategy (e.g. PyImport_ImportModule() and
PyEval_CallObject()), I get a core dump without a traceback.

Thanks, Craig Rendon (c.rendon at attbi.com)
