[racket] raco exe difficutly with Release 5.3.1 & stateless web server

The (require (for-syntax racket/match/parse)) solved the executable 
problem. Thanks.

I have a second raco exe issue--

  and I don't think this is related to 5.3.1 b/c I believe I encountered 
similar problem earlier today using raco with 5.3

This is also using different underlying source code than the earlier 
problem (which is now resolved)

Apparently compiled program is having trouble with flomap-struct.rkt 
and/or flomap-stats, as documented below.

However, I've verified that racket-provided file is present (and 
unmodified)

Is there anything obvious from the error message to do or should I 
isolate the bug further so you can reproduce?
