I've been attempting to install rvm and it fails when installing Rails on my Mac with 10.8.4. If anyone can explain how to fix this problem, I would appreciate it.
ERROR: Could not find a valid gem 'rails' (>= 0), here is why:
Unable to download data from
http://gems.rubyforge.org/ - Errno::ETIMEDOUT: Operation timed out - connect(2) (
