Thank you for suggesting these steps thechartist. Unfortunately, I think I am out of luck: 

[~]$ cd App-perlbrew/
[App-perlbrew]$ git pull
Already up-to-date.
[App-perlbrew]$ perlbrew self-install
You are already running the installed perlbrew:

    ~/perl5/perlbrew/bin/perlbrew
[App-perlbrew]$ perlbrew init

perlbrew root (~/perl5/perlbrew) is initialized.
[App-perlbrew]$ perlbrew available

ERROR: Unable to retrieve the list of perls.

[App-perlbrew]$

  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
