This is the error message I'm getting, with perl 5.8.8 on linux:

So it might be a problem in connection with ActivePerl or your particular installation. Just a wild guess

When I used RecDescent the last time I put only function calls into the parser code. The functions I put outside the parser into a different module so that I could get meaningful line numbers from the error messages.
