the minicpan script is ass. But then it was written as an article, not as
a highly efficient piece of code.

syncs a hell of a lot faster and makes two rsync connections rather than
a vast number of HTTP requests.

Meh. CPAN doesn't delete anything from ~/.cpan/sources, ever, normally. So
you start from an empty site_perl and an empty local::lib, wipe that, do
a 'make installdeps' on your app, verify it (this being essential to ensuring
you've got all the deps into Makefile.PL anyway), then you just rsync that up
and the CPAN.pm on the far end has the exact set of tarballs it needs.

Much more bandwidth efficient :)
