# Copy the gem location to clipboard
bundle show yajl-ruby | pbcopy
# Example: /Users/gedrovits/.rbenv/versions/1.9.3-p484/lib/ruby/gems/1.9.1/gems/yajl-ruby-0.8.2
cd <cmd + v>
cd ext/yajl
# Now we need to replace 'inline void' to 'static void'. This will also create backup of old files.
sed -i '.bak' 's/inline void/static void/g' yajl_ext.h yajl_ext.c
# Now we must rebuild changed extension
make clean all
# After this you should not have any problems with yajl-ruby

Ruby, RVM and Mountain Lion

Key problems

Mountain Lion (10.8) has three main difference compared to Lion (10.7):

• XCode 4.4 does not install Command Line Tools by default
• X11 isn't available anymore
• The installed version of OpenSSL has some bugs

How to work around

source 'https://rubygems.org'

gem 'rails', '3.2.3'

# Gems used only for assets and not required
# in production environments by default.
group :assets do
  gem 'sass-rails',   '~> 3.2.3'
  gem 'coffee-rails', '~> 3.2.1'
  # See https://github.com/sstephenson/execjs#readme for more supported runtimes

$ rails console
Loading development environment (Rails 3.0.6)

Gives you a handle of all the routes (config/routes.rb)

#Inspect a named route:
