[Haskell-beginners] not able to compile Happy GLR files

[trailblayzr]

I'm unable to compile the GLR examples (in the 'glr' directory) provided 
with Happy, version 1.16. I'm using ghc version 6.6.1. I've looked at 
the version of Happy currently in darcs and the pertinent part of the 
examples has not been updated there, either. This Happy seems out of 
date because it uses the flag "-package data"; my searching indicates 
that the 'data' package is old. Other errors remained after I removed 
the flag. Would someone please verify the error? Also, does anyone know 
of or have a GLR example that works?

Thank you for reading or helping.
