Re: CPAN install module error

Linux 2.6.18-308.13.1.el5PAE

I have bad news for you. That's CentOS 5 which is hitting EOL a week tomorrow. You would do much better by switching to some other operating system with support extending beyond this month.

If you want to install modules aside from those already available via yum then the cpan tool is not the only option. You may also install the modules by hand which IME gives you better control over the process.

The actual problem you are facing, however, is that you are using the wrong module name. Compare

I have a problem downloading Perl module 'Log::Log4Perl'

with

# cpan -i Perl::Log4Perl

Spot the difference?
