Re: Installing cpan or cpanm modules on a behind-firewall machine with no Internet connection

App::cpaminus (respectively http://cpanmin.us) is a self-contained single file, so you can copy it as you like.

For your development environment, I really, really recommend that you have a Perl 5.8.x readily available for testing because 5.8.x is really far behind the times and there are many modules that have problems with the module versions shipped with 5.8. Testing your stuff against 5.8 is important.

For the long term view on deployment, in your case I would look at CPAN::Mini or Carmel or Pinto to maintain your own curated CPAN mirror that gets synchronized from time to time with the mainstream CPAN but is usable from within your network.

Thank you. How can I install 5.8 on my local server? I'm on Mac OSX, or Linux. I already have 5.18 on Mac and 5.16 on my Linux box. Is there a way to have two Perl installs on the same server, or downgrade Perl on a box?	[reply]

One method for installing multiple Perl versions on the same system would be to use perlbrew.	[reply]

In addition to dasgars comments, leave the system/default `perl` alone. It belongs to the system maintainer/OS vendor. Changing the system `perl` means that security upgrades to modules will not work anymore or will break your existing installations. Compile your own version(s) of Perl manually or using perlbrew.
