I do have perlbrew installed

So then there is no problem right?

Do you want to solve it, yes or no?

When you type "perlbrew"  which perlbrew is run? using which perl? What is shebang of this  which perlbrew?

If perlbrew cannot find the corresponding App::perlbrew then its not installed :) where you want it

Simple solution, install the module, then install it using perlbrew into one of your perlbrew perls, then set this as your default perl as first perl in your $path

There is a problem. Or perhaps several problems. First I cannot even type perlbrew list. I get the message saying it cannot find App/perlbrew.pm

I can't remember the response I got when I type 'which perlbrew', but it certainly was not what I expected.

I am restoring xubuntu 13.10 now. But that leaves me the problem still of how I am to upgrade my xubuntu 13.10 to 14.04

Why roll back? Why not just install perlbrew again? Also, you forgot to login.

Ah, upgrade your expectations? :)

Simply install perlbrew again?
