Perl modules may be installed using the CPAN module or from source.
\nCPAN method<\/p>\n

perl -MCPAN -e shell (to get an interactive CPAN shell)
\nperl -MCPAN -e ‘install Time::JulianDay’ (if you know the name of the module, you can install it directly without interacting with the CPAN shell)<\/p>\n

Within the CPAN shell:
\ni \/expression\/ will search for a Perl module containing expression, and
\ninstall module will install the module.<\/p>\n

Example:
\nperl -MCPAN -e shell
\ni \/JulianDay\/
\ninstall Time::JulianDay<\/p>\n

Note: if you are behind a firewall, you may wish to use passive FTP with Perl’s Net::FTP module. Set the environment variable FTP_PASSIVE 1 (or any non-zero value) to use passive FTP when downloading Perl modules through CPAN.<\/p>\n

Manual installation<\/p>\n

To manually install a Perl module:<\/p>\n

1. Download the Perl module from CPAN or other site.
\n2. Extract the tarball.
\n3. Run perl Makefile.PL
\n4. Run make
\n5. Run make test
\n6. Run make install<\/p>\n

Note: you should use the same compiler to build Perl modules that you used to build Perl. For example, if you are building Perl modules with gcc and are using a version of Perl that was supplied with your distribution (ex. Solaris 8 includes Perl 5.005_03), you may run into errors.<\/p>\n

Checking for existence of a Perl module
\nAn easy way to check for the existence of a Perl module on your system (technically, in Perl’s @INC array, a list of directories Perl searches when attempting to load modules) is to run perl -e ‘use module;’<\/p>\n

Example:<\/p>\n

perl -e ‘use HTML::Parser;’<\/p>\n
