Ah well, egg on face and all that.

I've uploaded a new version of my iTunes visualizer with Scheme REPL. 
The version I uploaded previously was accidentally linked against libgambc.dylib and required that to be in the right place to work.
This version is correctly linked against libgambc.a and should work even if you don't have Gambit installed. 

For anyone interested, you can download scmviz.tar.gz 

If you download it and unpack the archive, you'll find a README file with instructions.

Thanks, and sorry for any inconvenience caused by the faulty version.
