Have a possible fix in trunk. Give it a try.

I tried to setup a new application using the latest source code form trunk and mongodb.  I get the error pasted at the end when I try to register a new user in my app.  I tried changing the "from pymongo import son" to "from bson import son" in the dal.py with no luck.  I can import son from bson within the python shell.

 

I am running on mac osx lion (using macports python 2.6), pymonogo 2.2 (macports), mongodb 2.0.6 (macports) and web2py (2, 0, 0, datetime.datetime(2012, 6, 9, 17, 47, 2), 'dev')

ImportError: cannot import name son

Thanks,  The latest trunk sorted out the import error. I also changed 

#import pymongo.objectid --> import bson.objectid

and replaced all references.  With my limited testing so far it seems to be working.  

If I try to register a new user with auth in mogodb I get the same error reported here: https://groups.google.com/d/topic/web2py/KQKqaKEpgu4/discussion

Can you email me a patch with your change.
