Thanks for your replies and yes, I could make it open to root and me, but I think I'd want a different collection of modules for each version of Perl in cpan (some new modules won't work on older Perls), so how would I patch cpanm to be different for all the Perls available in perlbrew?

A bit of a faff when I thought perlbrew had self-contained environments.

I'll look into it more...!

Cheers,
