You need to use the old require format for the older PLT version.

   (require (lib "readerr.ss" "syntax"))

However, my attempt to test Eli's code out led to a new problem:  
regexp-try-match does not seem to be part of v372.

Still, the hint above may get you far enough to port Eli's code.  (I  
did not attempt to do so.)
