How can I create a portable strawberry with extra bundled modules?

The portable strawberry perl is a godsend-- I can bundle it into an NSIS installer along with the actual scripts and have the user double click it. However, I'm still having to install CPAN modul开发者_开发知识库es that our scripts need, manually on each user's computer.

Is there a portable way to 'inject' cpan modules into strawberry perl's portable version?

Would it be a good idea to take the portable strawberry on a development machine, install modules via CPAN, and re-zip it for distribution? (I imagine I'd need to fix the install location to c:\custom-perl or something if I do this). Anyone know of a more direct way? I suppose I should script the cpan commands into the installer, but it would be nice if the user didn't have to wait 20 minutes+ for the installer (which is how long it takes to compile all dependencies).

I think if you use one of the CPAN tools (cpan/cpanp/cpanm) it should install just fine to Z:\<strawberry path>\perl\site\lib and then you can pack the whole thing up.
