I did some more testing on this on a system that's basically OpenPKG
Release 2.3 with a few CURRENT packages that require frequent updating
(e.g. clamav, spamassassin, etc.).  The version I build by copying the
_bsddb.c file from the current CVS failed with the traceback attached here.

Today I tried what is probably an extreme measure, and patched the python
tree with the current CVS tree which now works, but may well introduce
other issues.  This built, and seems to work OK, at least as far as the
bsddb module is concerned.

I backed off from that a bit as that was really python-2.5.alpha something
or other.  I did a cvs checkout on the release24-maint tag, which I presume
is basically maintenance.  After some fiddling with the python.spec file,
largely to debug the failing install, I have a working source package at
URI below.  The patch file is rather large, so I'm not going to post it to
a mailing list.

ftp://ftp.celestial.com/private/ftp.openpkg.org/release/2.3/SRC/python-2.4-20050307.src.rpm

I would like to suggest that in interests of stability on the OpenPKG
Release 2.3 tree, that the Berkeley db package be back dated to the
db-4.2.52.2-2.2.0.src.rpm version.  I would like to see another cycle of
testing in the CURRENT tree before declaring this stable.
