title: Can I install MacTex on a machine with Homebrew without permission (or other) issues?
body: <p>I currently have a working MacTex 2014 installation and Homebrew installation on OS 10.10.3, and am about to install MacTex 2015. But I'm concerned about permission issues. Both packages install in <code>/usr/local</code>, and Homebrew requires very specific permissions on that directory to function.</p>
  
  <p>Will installing MacTex 2015 change <em>anything</em> in my Homebrew installation? Will it in any way affect how Homebrew works?</p>
