there might be a few things your confused by. [1] is the link to the  
parse tree project page. PT is a C extension. RP uses racc which has a  
C extension to optimize its performance. A majority of racc is  
implemented in ruby.

it is, the C extension ships with the ruby distro. This is an updated  
release, but most if not all of the updates pertain to the racc  
compiler, which does NOT ship with the ruby distro. It won't be rolled  
in.
