If unrecognized/error then:
Code:
wget --no-check-certificate -O - http://install.perlbrew.pl | bash
then/otherwise proceed with:
Code:
perlbrew install perl-5.12.3
Now to switch to that version:
Code:
perlbrew switch perl-5.12.3
Recompile server.
Should you wish to revert the change of Perl version to back what you're running:
Code:
perlbrew switch perl-5.24.1
I use Ubuntu, so, can't specifically state success rate on other nix flavors.
