Juan,

This more and more seems like an Oracle Client issue:
- Do you have several Oracle Products Installed?
- In which order were they installed?
- Do you have several Oracle Homes?
- What is the order of the Oracle Homes?
- Which Oracle Home is detected First?

This file is included when you Install the Oracle Development packages (i.e.
OCI development, etc...) there is an option in the Oracle Client CD to
install this.

Note(s) to Matt:
================
1) What version of the Oracle Client are you using to build DCO2?

2) I have Zope 2.4.0 and separately I have ActiveState python 2.1.1. The
install.py file looks at the Active State python rather that the on supplied
for Zope, and thus fails for my python, even though the modules should be
binary compatible for both 2.1 and 2.1.1. I also suggest changing the check
to include "2.1.1" for now.

3) I also suggest clarifying the installation document to add a manual
installation section and here say something like "if you want to make a
manual installation, copy the appropiate module for your platform from the
'binaries' subdirectory to the 'DCOracle2' subdirectory (i.e. side by side
with the 'DCOracle2.py' file) and rename it  to 'dco2.pyd'"

4) What are you using on windows to compile the module? from the projects
files I guess "Visual C-something" from Microsoft. Can I use other compilers
(cygwin, the free borland stuff, etc)? if visual-c something, what version?


Sincerely,
