I've seen this problem before. In addition to the workarounds
suggested by Matt Austern, you should do the following:

(1) Register with the Apple Developer Connection and obtain
the latest December Developer Tools update from
http://connect.apple.com

(2) Set the environment DYLD_BIND_AT_LAUNCH variable to 1.
This trick was suggested to me by Peter O'Gorman, for working around
the exact same problem that you posted. See the thread:

http://lists.apple.com/mhonarc/darwin-development/msg16670.html

The bug which you described is the same as Radar bug 3012645.
