Howto install perl modules

I often find myself trying to install (binary) packages that have dependencies to perl modules.

Because I work on varying platforms, sometimes RHEL/RedHat, CentOS, sometimes Debian based, like Ubuntu, and sometimes, less often now, but maybe I will go back again, to Gentoo. In many ways my ideal platform.

However, Perl is wicked, and the concept of perl modules in a package manager is even more crazy.

What are we going to do when we need a new version of a software (say, amavisd-new) that is not available in the distros package library?

I’m thinking, build from source and you can’t go wrong, right?

In the case of amavisd-new, these are the listed prerequisites:

Archive::Zip   (Archive-Zip-x.xx) (1.14 or later, currently 1.23)
Compress::Zlib (Compress-Zlib-x.xx) (1.35 or later, currently 2.008)
Compress::Raw::Zlib (Compress-Raw-Zlib) (2.017 or later)
Convert::TNEF  (Convert-TNEF-x.xx)
Convert::UUlib ( (1.08 or later, stick to new versions!)
MIME::Base64   (MIME-Base64-x.xx)
MIME::Parser   (MIME-Tools-x.xxxx) (latest version from CPAN - currently 5.425)
Mail::Internet (MailTools-1.58 or later have workarounds for Perl 5.8.0 bugs)
Net::Server    (Net-Server-x.xx) (version 0.88 finally does setuid right)
Digest::MD5    (Digest-MD5-x.xx) (2.22 or later)
IO::Stringy    (
Time::HiRes    (Time-HiRes-x.xx) (use 1.49 or later, older can cause problems)
Unix::Syslog   (
BerkeleyDB     with bdb library (preferably 4.4.20 or later)
Mail::DKIM     (Mail-DKIM-0.31 or later)

So, if I’m going to install amavisd-new, from souce, on a RHEL6 server, what do I need to do? -Well, I’ll show what I did. Not neccessarily what is the best thing to do… OK?

yum install cpan
perl -MCPAN -e shell

(going with the defaults, automatic is nice)

When I attempted to install the first module (Archive::Zip), I discovered that I did not have web access from my server, so I had to download the CPAN modules by hand. I did this by using the powerful search tool, and just pasting the package name (Archive::Zip) in the search box and then downloading the tar.gz packages one at a time.

Manual installation of 1 CPAN package:

tar zxf Archive-Zip-1.31_04.tar.gz
cd Archive-Zip-1.31_04
perl Makefile.PL
make test
sudo make install

Had I had internet connection available:

perl -MCPAN -e 'install Archive::Zip'

The beauty of CPAN installation is that it resolves dependencies automatically.
