I have a perl script that needs a long list of prerequisites. While installing these, I am not getting past the installation of HTTP::Message

When I run cpan HTTP::Message from the command line as root, I get the following output:

cpan HTTP::Message

Reading '/root/.cpan/Metadata'

Running install for module 'HTTP::Message'

Running make for G/GA/GAAS/HTTP-Message-6.06.tar.gz

Checksum for /root/.cpan/sources/authors/id/G/GA/GAAS/HTTP-Message-6.06.tar.gz ok

CPAN.pm: Building G/GA/GAAS/HTTP-Message-6.06.tar.gz

Checking if your kit is complete...

Looks good

Warning: prerequisite Encode::Locale 1 not found.

Warning: prerequisite HTTP::Date 6 not found.

Warning: prerequisite IO::HTML 0 not found.

Warning: prerequisite LWP::MediaTypes 6 not found.

Warning: prerequisite URI 1.10 not found.

Writing Makefile for HTTP::Message

However, I have run cpan individually for all of those prerequisites (as root), and the install succeeded.

What am I missing here?

I am running CentOS Linux release 7.1.1503 (Core)

    What's wrong with just doing yum install perl-HTTP-Message? Why are you trying to use CPAN? You should avoid using CPAN when the perl modules are already packaged. – Michael Hampton Apr 27 '15 at 18:29
  • Thanks @Michael, that worked!! If you add your advice (use YUM rather than CPAN where possible) as an answer, I'll mark that as the resolution to my problem :-) – Joon Apr 27 '15 at 19:35
  • Are you sure you setup CPAN to auto-install dependencies? It's part of that wizard that launches the first time you run it. From perl monks, you can rerun the wizard with the following two part command: "rm /etc/perl/CPAN/Config.pm ; perl -MCPAN -e shell" I usually use 100% default values. – Some Linux Nerd Apr 27 '15 at 20:23
  • @SomeLinuxNerd, I have that option enabled, CPAN was just not installing that module, its compilation failed saying that the dependencies are not there (even though they are!!). Installing the Yum package worked. – Joon Apr 29 '15 at 15:36
