[racket] Error running whalesong: wrong number of fields for structure mod: expected 16 but got 15

Joe,

>> I've been pulling and building directly

Thanks very much for this, but I'm not at all competent on racket 
internals

Could you please sketch out where to place the files and how to build 
them?

I won't need help after that.

Sorry to bother.

Thanks again.
