I was able to cd into App-perlbrew and then perl perlbrew self-install and perlbrew is working but whenever it needs to connect to internet those specific commands are failing.

[~]$ perlbrew
Usage:
    perlbrew command syntax:

        perlbrew <command> [options] [arguments]

    Commands:


[~]$ perlbrew list
[~]$ perlbrew available

ERROR: Unable to retrieve the list of perls.

[~]$




[~]$ perlbrew install perl-5.28.1
Fetching perl 5.28.1 as ~/perl5/perlbrew/dists/perl-5.28.1.tar.gz
Download http://www.cpan.org/src/5.0/perl-5.28.1.tar.gz to ~/perl5/per
+lbrew/dists/perl-5.28.1.tar.gz
Installing ~/perl5/perlbrew/build/perl-5.28.1/perl-5.28.1 into ~/perl5
+/perlbrew/perls/perl-5.28.1

This could take a while. You can run the following command on another 
+shell to track the status:

  tail -f ~/perl5/perlbrew/build.perl-5.28.1.log

Installation process failed. To spot any issues, check

You might also want to try upgrading patchperl before trying again:

  perlbrew install-patchperl

Generally, if you need to install a perl distribution known to have mi
+nor test
failures, do one of these commands to avoid seeing this message:

  perlbrew --notest install perl-5.28.1
  perlbrew --force install perl-5.28.1

[~]$ perlbrew install-patchperl

ERROR: Failed to retrieve patchperl executable.

[~]$

[download]

The log file ~/perl5/perlbrew/build.perl-5.28.1.log has only one line sh: patchperl: command not found

Seems like my Linux machine is having problem in letting perlbrew connect to internet. :-(
