in reply to Change Namespace of Package

It sounds like you don't need to use both version 7 and 8 from the same script, which makes things easier (if you did, that'd make things pretty complicated). You could install the modules to different, custom library paths. Hopefully, the modules use one of the standard Perl installation procedures: If it's ExtUtils::MakeMaker, run perl Makefile.PL INSTALL_BASE=/path/for/v7 resp. /path/for/v8 (the paths where you want to have the libraries installed); if it's Module::Build, run perl Build.PL --install_base /path/for/v7 resp. v8. Then, in your Perl scripts, you can point them at the correct library path, for example with use lib '/path/for/v7/lib/perl5' before loading the module.

    This is exactly what I needed! I tried for a while to only install only one version to a custom installation location but had issues. Once I gave up on that placed both versions of the package in a custom location (as you recommended) things worked perfectly! Wahoo! Much thanks!

    I prefer to install two builds of Perl rather than much with additional include paths. It's super easy with perlbrew, and you don't have to worry about setting the environment right or about different dependencies or version of dependencies, etc.

      Can perlbrew also replicate the installation of my prefered modules, like Data::Dump ?

      update

      OK that's rather an issue when having different Perl versions, because otherwise one can share the same lib path.

        I'm not sure what you're asking. perlbrew doesn't replicate installations. It's a Perl installer and a path-management utility for the shell. But once it installs a build of Perl, you are free to install Data::Dump for it.
