[Zope] Python/DBI/ODBC/Zope

We have a Python program that reads a URL, rips it apart and dumps the pieces into an ODBC connected database. Works fine from the command line. If we try to add this into Zope as an External Method, it states it cannot find the dbi component. import dbi uses a dbi.dll in Windows. This was developed on 2.1 Python but the dbi module exists in Zopes 1.52 Python so I am not sure where the problem is. Thanks Allen
