Worked great for me. Thanks for posting this.

Am I missing something or is the post above regarding the _bsddb module hack incomplete? What file did you actually hack below — I don’t understand how the logic flows below and what file you are actually editing…

I managed to get it to work though by installing bsddb3 from the pybsddb site and hacking the file /System/Library/Frameworks/Python.framework/Versions/2.5:
marc@hyperion:~$ diff -u dbhash.py.orig dbhash.py

# prevent a second import of this module from spuriously succeeding

And actually, the code used to state “import bsddb”, which produces an error itself. “import dbhash” does work w/o problem as you show.

Nice post. I’ve followed your instructions and can import dbhash, but am still getting the following code error:

dbm = bsddb.hashopen(bdb_name, ‘n’)
NameError: global name ‘bsddb’ is not defined

Any advice you have will be much appreciated.

Thanks,

-k.

Hrm. Long story, but I’m trying to get cvs2svn to work on Leopard, and that requires a working bsddb module.

I can’t actually get pybsddb to build:
distutils/sysconfig.py”, line 389, in _init_posix
raise DistutilsPlatformError(my_msg)
distutils.errors.DistutilsPlatformError: $MACOSX_DEPLOYMENT_TARGET mismatch: now “10.4″ but “10.5″ during configure

How did you get on with that part?
