We have some dependency issues in razor-client involving the unf gem:
1. If we use 0.1.4, the latest released version, native extensions need to be installed. This requires gcc on Ubuntu, and both gcc and gcc-c++ on Centos, to be installed. 1.9.1 and prior both require this.
2. If we use 0.2.0.beta2, a prerelease version, the install happens without native extensions. However, the gem install command needs the --pre flag.
The Gemfile cannot say ">= 0.1.4" and still pick up the prerelease gem, so we must choose a path. There's a third option:
3. We fork and release the 0.2.0.beta2 gem as a full version.
1.9.1, the last version of razor-client, did option 1, so we will stick with that.
