Following up on my own post here: archiving .cpan, and archiving perl
library directories, works fine for installing the built CPAN and modules
on another [identical] machine, by simply unarchiving those bundles.

Now I am at another phase: a machine built this way needs a few more CPAN
modules installed, and has no network access.  How do I install?  If I had
network access I would do e.g.:

cpan List::Util List::MoreUtils XML::Simple

So I tried:

cpan Scalar-List-Utils-1.23.tar.gz

which doesn't work; then I tried:

cpan GBARR/Scalar-List-Utils-1.23.tar.gz

which wanted network access and failed.

I am aware of Mini but don't need a mirror - I just need a reasonably
simple way to add a few more Perl modules to a unit that already has many
modules installed via cpan.  Perhaps I actually need some tool other than
cpan for this purpose and am just not aware of it.
