I wanted to do some hacking on the gem but it was a pain to get the development environment setup. I've included bundler with the correct gems so the setup process is a easier.
Use "RSpec" insted of "Rspec" as its deprecated in v2.x
I would definitely like to add bundler integration but for now I didn't want to maintain two lists of dependencies (jeweler + bundler). Hopefully it won't be a problem with the new version of jeweler (Gemfile support is currently in jeweler master).
Anyway the webmock Gemfile will require splitting dependencies across runtime, dvelopment and test group. It will also require platform directives, since some of the gems are not supported on jruby.
Ah that makes sense.
