issue with running tests and loading active_support from Rails gems instead of edge copy

Is anyone else seeing this issue when running the test suite against edge?

I applied the patch that David supplied and it fixes the issue, so I'm
assuming that other folks must be seeing it. It appears that the
active_support gem gets loaded, instead of the edge copy involved in
the test run.

We are also seeing it with action mailer tests, which I opened a new ticket for:

thanks,

Works for me too, so I'm not sure what's up. Does it happen before:

Could you git-bisect and track it down?
