Math::Pari module

finfan has asked for the wisdom of the Perl Monks concerning the following question:

I need to use this module. I am attempting to install it via cpan. The 'make test' fails with 14 of the following errors (all similar, just different files). Any ideas

        Test returned status 2 (wstat 512, 0x200)

I guess that you are actually trying to install Net::SSH::Perl for which, Math::Pari is a prerequisite. Nowadays, using Net::SSH::Perl is not the best thing you can do. It is an old module, mostly unmaintained, with lots of unsolved known bugs. Instead, try using Net::SSH2, Net::OpenSSH or Net::SSH::Any.	[reply]

Thanks everyone for the help. The problem ended up being SELinux not liking the Math::Pari module. Just did a setenforce 0, installed Net::SSH::Perl with the force command (CPAN Shell), and then turned selinux back on. Working great. Superdoc, appreciate the tip on the other SSH options. I've always found Net::SSH:Perl to be a bit cumbersome, but it's worked for me. Moving forward I will look at using your suggestions.	[reply]

One of the prerequisites for that module is the PARI library. I'm not very experienced with *nix type OSes, but based on the error message that you shared, it looks like you either don't have the PARI library installed or don't have permissions to access the PARI library.	[reply]

Hi finfan, How are you installing your module? If you have cpanm installed on your system, you can simply install Math::Pari module from the CLI like thus: `sudo cpanm Math::Pari` I just did without any stress whatsoever. If you tell me, I'll forget. If you show me, I'll remember. if you involve me, I'll understand. --- Author unknown to me	[reply] [d/l]

Just as a quick check, are you running under sudo or as root while installing from CPAN? The permission denied looks a bit like what I would expect if I were running as a non-privileged user... ...the majority is always wrong, and always the last to know about it... ..by my will, and by will alone.. I set my mind in motion	[reply]
