I'm using both 22.2(in terminal) and 23.0 in Emacs.app on my MacBook Pro, 

both installed by MacPorts. 

There is no critical problem, almost everything are smoothly running, except the 

vc mode. It runs perfectly in 22.2 in terminal, but never really work in Emacs.app.

When I open some file which IS under source control (svn or git), it says 

'Load vc-git...done' or something like that (no errors), but the mode actually 

not activated. It's really annoying.

Any suggestions? Or just some similar situation that have been mentioned here before?

Thanks.
