Not multiple post ... this is a second copy.

It does not work for me on Lion (I've never tried Snow Leopard).  As 
valgrind does not yet (even in the recent 3.8.0) really support 
Mountain Lion and we will be upgraded shortly (and BTW, Snow Leopard 
is now end-of-life for security patches), I've pretty much given up on 
valgrind on OS X.
