I found a similar problem described in: http://groups.google.com/group/sdruby/browse_thread/thread/d3ba3a487714bdb4?pli=1
I installed build-essential ruby-dev 4.2 libruby1.8-dbg and retried 'sudo gem install rub-debug' after this, the gem installed correctly. I suggest that there are missing dependencies on the ruby-gems package.
