Cucumber will accept multiple -r or --require. It simply pushes all the 
requires onto a stack and requires them all.

Looks like this is a polygot problem. Aslak recently forked and patched 
a copy of Treetop to avoid the dependency on this:

git://github.com/aslakhellesoy/treetop.git

I would suggest you try and install treetop from this source and see if 
that fixes the problem.
