cpanm as a root, it automatically sets up local::lib compatible
installation path in a C<perl5> directory under your home
directory.

To avoid this, run C<cpanm> either as a root user, with C<--sudo>
option, or with C<--local-lib> option.

=head2 cpanminus can't install the module XYZ. Is it a bug?

It is more likely a problem with the distribution itself. cpanminus
doesn't support or may have issues with distributions such as follows:

=over 4

=item *

Tests that require input from STDIN.

=item *

Build.PL or Makefile.PL that prompts for input even when
C<PERL_MM_USE_DEFAULT> is enabled.

=item *

Modules that have invalid numeric values as VERSION (such as C<1.1a>)

=back

These failures can be reported back to the author of the module so
that they can fix it accordingly, rather than to cpanminus.

=head2 Does cpanm support the feature XYZ of L<CPAN> and L<CPANPLUS>?

Most likely not. Here are the things that cpanm doesn't do by
itself.

If you need these features, use L<CPAN>, L<CPANPLUS> or the standalone
tools that are mentioned.

See L<cpanm> or C<cpanm -h> to see what cpanminus I<can> do :)
