Uninstall perlbrew
If you are like me, sometimes you want to start over. For perlbrew this is quite easy.
$ rm -Rf ~/perl5
And then clean your shell script (bash example), remove the following lines from your ~/.bash_profile:
#perlbrew
source ~/perl5/perlbrew/etc/bashrc
I have done this several times, but decided to include this brief discussion from StackOverflow.
