The app currently runs on either Linux or Windows, with either a local or remote database back-end (which is either PostgreSQL or MySQL).
I've got all the component Perl modules gzipped (using 'make dist' in each module's own development sandbox).
Right now, I have to (for example) burn all of the needed modules (my custom ones, and a bunch from CPAN) to CD, copy them to the new system, and then manually make/make test/make install each of them, in a certain order.
I was going to just write a script to do this, but then thought that there might be a better / canonical way of packaging and installing Perl applications. :-)
