title: Gem causes builds to fail. Point to local lib?
body: <p>I am using a gem which was recently updated. The last update is causing my builds to fail (uses uncompiled <code>SCSS</code> inside a <code>.css</code> file). I fixed the issue and created a pull request, but the author is not responding to the issue I opened and / or merging my PR. </p>
  
  <p>Would it be a good idea to store the gem locally, push it to my production and staging and point to it from the Gemfile until the issue gets fixed in the main repo? </p>
