Install rb-fsevent gem in a Mac OS X without XCode
As I do not have XCode installed in my MacBook (because I use this wonderful solution), I recently ran into a problem with rb-fsevent gem installation.
This gem compiles using some environment stuff that XCode provides, which I didn't have.
So a solution for using this gem is to switch to the following branch on ttilley repo:
gem 'rb-fsevent', :git => 'git://github.com/ttilley/rb-fsevent.git', :branch => 'pre-compiled-gem-one-off'
And it works!
From an issue in rb-fsevent repository.
