Where does CPAN install Perl modules in OS X?

Question

Just curious where CPAN installs all the Perl modules by default in OS X.

Answer 1

Besides system defaults, you may have configured your CPAN client to install the modules somewhere else. So have a look to your config:

$ cpan
cpan> o conf makepl_arg
cpan> o conf make_arg
cpan> o conf make_install_arg
cpan> o conf mbuildpl_arg
cpan> o conf mbuild_arg
cpan> o conf mbuild_install_arg
cpan> exit

Ask it!
