title: Perl Update in OS X 10.10.5, Cannot Locate Perl Modules
body: <p><strong>UPDATE:</strong> I tried again and realized that perl said that when it tried to load the module, it got a "permission denied" error. So, I just re-ran the script using sudo...and it worked. I guess it must be some sort of permissions changes.</p>
  
  <p>Original:<p>
  I just updated OS X to 10.10.5 and suddenly, Perl can no longer locate any of my CPAN-installed modules. Even newly installed modules are not found. I know that the update installed Perl 5.18.2, but even when I explicitly use 5.16, the modules still cannot be located.</p>
  
  <p>The output of perl -V is here:</p>
