Error installing sqlite 1.8.3 (mac OS X 10.9.5) - Ember

I'm trying to run $ bundle install on the Ember Course Demo and without fail (every workaround I've tried has not worked) has resulted in the same error. Certain installs have completed, however they have not solved the problem and allowed me to run this locally.

Here is the link ember course demo. I've followed all the directions multiple times and my rbenv functions properly. It appears only to be on bundle install. gem install sqlite3 -v '1.8.3' works, but does not solve the problem. Any suggestions would be greatly appreciated.
