[racket] External connection to Finndesign Liitin

If I run liitin.rkt (either on the command line or in drracket) it
complains there is no #lang line. When I add one I get this error

compile: unbound identifier (and no #%app syntax transformer is bound)
at: quote in: (quote (quote gaia:fibonacci:2011-01-01T12:00:00))
