On reflection, my working hypothesis to achieve nirvana and a future proof toolchain to an EXE is to:
* Install Strawberry Perl from our locally maintained distribution
* Use the method described in http://digitalcrunch.com/perl/how-to-use-par-with-strawberry-perl/, and work with appropriate teams to grab the 5 tarballs.
Being a total novice to this sort of thing, I've no clue if 'dmake' somehow arrives with Strawberry Perl, or if there is some other dependency I need to satisfy, or even if it will run at all on my local machine ...
