keep getting error when trying to install gems on osx, undefined method `ord' for nil:NilClass

Question

I am using rvm on osx, I have only one version of ruby currently installed 2.0.0 and every gem install I try to run comes back with the same result:

guys-MacBook-Pro:guy guy$ rvm use
Using /Users/guy/.rvm/gems/ruby-2.0.0-p353

guys-MacBook-Pro:guy guy$ gem install proxylocal
ERROR:  While executing gem ... (NoMethodError)
undefined method `ord' for nil:NilClass

please help

thanks
