installs the wrong gems

[frenesim]

Hi all. Doing gem install statsample-glm installs https://github.com/AnkurGel/statsample-glm gem and not this one.

Since I'm using bundler I'm going around this using gem 'statsample-glm, git: 'https://github.com/SciRuby/statsample-glm.git

The same problem happens when doing gem install sciruby-full or using gem 'sciruby' in the Gemfile.

This can be quite frustrating to someone that wants to do a quick try on SciRuby library and he his starting with GLM.

I don't know how exactly I could help more, but I'm glad to follow some guidance and to adapt readme file and the dependencies.
