Cool, thanks Mathias.  I'm still using `gdc-11` on the play 
machine.  I tried `dub` with vibe.d and it's borked on this 32bit 
laptop.  Probably simple, but at this point on the learning 
curve, the hassles with dmd and dub are keeping me away from 
those tools.  Might be soon to those steps, but not today.  ;-)  
Bookmarks made to revisit this thread when the time comes.

I do look forward to attaining a more complete grasp of the D 
space.  The hint that Ali passed on about `version` settings not 
carrying through to imports helped enough that I'm pretty happy 
with the plans for now.  They might be wrong headed plans in the 
grand scheme, but for now, things are working out.  A bunch of 
stand alone CLI programs, with a boss that can manage them all, 
without need of shelling out a process.

Have good, make well
