Re^3: how to test my perl-prerequesites on a Linux-box - with command line-approach

[Corion]

I seriously recommend you learn about your operating system and how to do things with it.

The output seems to suggest to me that you ran the first command I showed you, look WWW::Mechanize::Firefox. What happened when you ran the other commands that were to be run after that one?

Please work on your reporting capability. If you want to get immediate answers, please put some effort in your question and provide all relevant information. If you don't understand instructions given to you, either try them all out and live with the consequences or ask before you try them out. Doing system administration through this forum is quite tedious, so I recommend that you find somebody who is willing to set up your system for you, or who is willing to teach you how to operate the system yourself. I am not that person.

I see that you are using the system perl to install modules from CPAN. This is highly recommended against. Use your OS package manager or talk to your system administrator how to install Perl modules for the system perl. The recommended way for a Perl developer is to install Perl modules locally (see local::lib) or to compile their own private version of Perl (see App::perlbrew).
