Hello!
Thanks for all greate help before. Even though I already knew that I found the problem, people here has a tendency to bring more than I already knew. I hope you once again can help me here.
Skill level: Complete beginner
Summary (and question): I tried to install Crypt::Random, but faced some problems. Those were hunt down and solved by installing Math::Peri (dependency) separately. It made me wonder: How would you, the skilled Perl hackers, troubleshoot installation of Perl modules in CPAN (like the scenario below)? I found one solution, but is there a better one?
Longer: Today I was about to install Crypt::Random though CPAN and I got an error:

It didn't help much except that it can't find Math/Pari. So I did what I thought was a good idea (still thinks), to install Math::Pari separetly but got an error:
cpan[5]> install Math::Pari Running install for module 'Math::Pari' Running make for I/IL/ILYAZ/modules/Math-Pari-2.01080604.tar.gz Has already been unwrapped into directory /root/.cpan/build/Math-Par +i-2.01080604-6jeupl Could not make: Unknown error Running make test Can't test without successful make Running make install Make had returned bad status, install seems impossible
Unkown error doesn't help much. Ofcourse I have been google-ing but didn't find anything (on the first 10+ seconds). I did another attempt, this time I had closed and restarted CPAN. This time I got a better error:

I saw gcc-not found. Installing it, still gave the same output when installing Crypt::Random, but installing Math::Pari caused some compiling which is good! After that installing Crypt::Random went perfect.

It all made me wonder though: how would the "correct way" to troubleshoot this problem? How would the skilled Perl hacker do in this case?
