Installing librets on OSX Mountain Lion with rvm

gistfile1.txt

# On OSX Mountain Lion, 'brew install librets' installs librets into the system ruby folder,
# not the current rvm ruby as it used to on older versions of OSX. The only work-around I've
# found is to take the librets.rb and librets_native.bundle files and copy them into the proper
# rvm ruby's folders.

# Best way - make desired version of ruby the system ruby.
rvm use system
which ruby
# return the current system version of ruby
ls -l /usr/bin/ruby

# link system ruby to desired ruby
ln -s /Users/Dan/.rvm/rubies/ruby-1.9.3-p286-falcon/bin/ruby /usr/bin/ruby
rvm use system
which ruby
# should be desired version of ruby

# Now install librets - should install for desired version of ruby
brew tap homebrew/boneyard
brew install librets


# Alternative way - copy the librets files into proper folders for the desired version of ruby.

# Set rvm ruby version and install  librets
$ rvm use ruby-1.9.2-p290
$ brew install librets

# Check to see if it worked
$ irb
> require 'librets'
