[Solved]Problem with new Perlbrew installation

[mascip]

EDIT: After 2h of investigations, i realised that i didn't have the latest version of perlbrew (0.60 instead of 0.61), and fixed it by simply doing:

$ perlbrew self-upgrade

SOLVED!
~ ~ ~ ~ ~

Hello, i've installed Perlbrew on a new computer last week and i have a problem: perlbrew list doesn't list the versions of perl that i have installed. On the other hand, perlbrew lib list works and displays: perl-5.16.3@devel Which is what i expect. And $PERLBREW_PERL is correct and equal to "perl-5.16.3";

I also have this error message when /home/user/perl5/perlbrew/etc/bashrc runs: bash: export: `/home/user/.perlbrew/libs/perl-5.16.3@devel";': not a valid identifier which comes up while the __perlbrew_activate subroutine is called.

Question 1: Any idea what is going on?

Question 2: I've tried to add print statements in the ~/perl5/perlbrew/bin/perlbrew executable, unsuccessully: i get strange bugs. Is that because this file is fatpacked, and it's not possible to modify the content of fatpacked files?

* Here is what i did last week to install it all:

I installed perlbrew with one of these two, i don't remember which one: wget --no-check-certificate -O - http://install.perlbrew.pl | bash or maybe curl -kL http://install.perlbrew.pl | bash

And then i did:

perlbrew install-ack
perlbrew install-cpanm
perlbrew install-patchperl
perlbrew init

And i added the following line in my .bashrc:

source "/home/user/perl5/perlbrew/etc/bashrc"

I have verified: the /home/user/perl5/perlbrew/etc/bashrc script runs.

Then i did:

$ perlbrew install 5.16.3
$ perlbrew switch perl-5.16.3
$ perlbrew lib create devel
$ perlbrew switch perl-5.16.3@devel
$ perlbrew lib list # prints perl-5.16.3@devel
$ perlbrew list # prints perl perl-5.16.3, and perl-5.16.3@devel
$ cpanm Archive::Any # worked without a problem

And this week i come back with the problem i presented.

Thank you for any help!
