8.45: How do I install a module from CPAN?

(contributed by brian d foy)

The easiest way is to have a module also named CPAN do it for you by
using the "cpan" command the comes with Perl. You can give it a list of
modules to install:

$ cpan IO::Interactive Getopt::Whatever

If you prefer "CPANPLUS", it's just as easy:

$ cpanp i IO::Interactive Getopt::Whatever

If you want to install a distribution from the current directory, you
can tell "CPAN.pm" to install "." (the full stop):

$ cpan .

See the documentation for either of those commands to see what else you
can do.

If you want to try to install a distribution by yourself, resolving all
dependencies on your own, you follow one of two possible build paths.

For distributions that use *Makefile.PL*:

$ perl Makefile.PL
$ make test install

For distributions that use *Build.PL*:

$ perl Build.PL
$ ./Build test
$ ./Build install

Some distributions may need to link to libraries or other third-party
code and their build and installation sequences may be more complicated.
Check any *README* or *INSTALL* files that you may find.

so please include as much information as possible and relevant in any
corrections. The perlfaq-workers also don't have access to every
operating system or platform, so please include relevant details for
corrections to examples that do not work on particular platforms.
Working code is greatly appreciated.
