after doing some googling on the `dyld: Symbol not found` issue i am
now trying a complete un and reinstall of opencv.
Perlmonks and the MySql dev teams have ran into issues before on snow
leopard where if you
try to mix 32 bit libraries on a 64 bit interpreter/ other libraries,
this issue can occur.

I'll update this thread if a 64 bit install of opencv doesn't fix the issue.
