Ruby cairo gem failing to install on Mac OS X Yosemite

Question

I am completely stuck on this. Working ruby on rails app that had dependency on cairo. After upgrading from Mac OS X Mavericks to Yosemite and doing a bundle install it fails to install cairo gem. I have tried playing around with the versions of gcc between 4.2 (apple's bundled patched version) vs 4.8 and 4.9 with no luck. Any ideas are welcome...

sudo gem install cairo Password:

Answer 1

I was able to work around this issue by installing macports

https://www.macports.org/install.php

Then installing cairo directly http://cairographics.org/download/

sudo port install cairo

Then gem install cairo worked.
