CPAN is an acronym for Comprehensive Perl Archive Network. It allows for downloading perl modules from the web.
Run CPAN like this:
# perl -mCPAN -e CPAN::shell cpan> install Foo::Bar
e.g.
cpan> install Math::XOR
You'll run that as root if your Perl is installed in a system-wide location. The first time you run that first command, you'll be prompted a number of questions to initially configure the module. For most of them, you just hit ENTER to accept the default.
Usecase
If you run a perl program and get the error message
Can't locate Net/DAV/Server.pm in @INC (@INC contains: /usr/lib/perl5/5.8.8/x86_ 64-linux-thread-multi /usr/lib/perl5/5.8.8 /usr/lib/perl5/site_perl/5.8.8/x86_64 -linux-thread-multi /usr/lib/perl5/site_perl/5.8.8 /usr/lib/perl5/site_perl /usr /lib/perl5/vendor_perl/5.8.8/x86_64-linux-thread-multi /usr/lib/perl5/vendor_per l/5.8.8 /usr/lib/perl5/vendor_perl .) at ./__webdav.pl line 14. BEGIN failed--compilation aborted at ./__webdav.pl line 14.
You see it's time to install Net::Dav::Server.
# perl -mCPAN -e CPAN::shell cpan> install Net::Dav::Server
