This occurred on a fresh download of PLT Scheme v370 as evidenced by  
the Welcome banner: "Welcome to DrScheme, version 370 [3m]". I am not  
building from source and removed my ~/Library/PLT Scheme/ directory  
before installing v370.

Once v370 was installed, I selected the Pretty Big language settings,  
did a "Run", restarted PLT scheme and followed the directions to load  
the PLAI teachpack. Restarted, once again, and followed the  
instructions at the DivaScheme web page.

It was at this point that the error occurred. Did I miss a step along  
the way?

As an aside, and I don't know if this is relevant, but I rename the  
topmost PLT folder in /Applications from "PLT Scheme" to "PLT". I  
only mention this as my ~Library folder contains a "PLT Scheme"  
directory. Might I have botched my installation?

Hope this helps, and if there is something you would like me to try,  
I would be more than willing.

Thanks,
