If you find you will need to install many modules, setting up your own $HOME/.cpan/CPAN/MyConfig.pm might be worthwhile.

You will need to touch entries like the following:

  'build_dir' => q[/home/me/.cpan/build],
  'cpan_home' => q[/home/me/.cpan],
  'keep_source_where' => q[/home/me/.cpan/sources],
  'makepl_arg' => q[LIB=/home/me/myperl/lib INSTALLMAN1DIR=/home/me/my
+perl/man/man1 INSTALLMAN3DIR=/home/me/myperl/man/man3],

Once you have done this, you will be able to install modules easily using:

perl -MCPAN -e shell
install Net::NetSend
