How to access Twitter go retrieve results from http://dev.twitter.com/doc/get/users/suggestions/:slug

Anyone know a suitable method to access results from:
http://dev.twitter.com/doc/get/users/suggestions/:slug ?

Apparently, the Twitter gem's current stable version does not support
the users/suggestions method. The Release Candidate (RC) versions do.
However, the RC versions are a little bit buggy. In fact, they
collide / have conflicts with other gems when one tries to restart the
Webrick web server.

Does anyone else know a better/alternative approach? Is there another
gem / method I can use until the Twitter gem is stable enough?

Why not just use curb or something similar?
