--- Comment #3 from hsteoh at quickfur.ath.cx ---
Thanks for taking the time to clarify.

I simply assumed it was downloading old releases because it needed to generate
tarballs and whatnot.  I've been on git master for too long, I don't even know
which official release we're on anymore. :-D

Is there any way to direct it to use the locally cloned and already-built dmd
instead?  I mean, it seems a little excessive to have to separately clone the
dmd repo when I already have one on hand.

Also, is the DIFFABLE=1 thing documented anywhere?  I admit I didn't look very
hard, I was just using the plain `html` target out of years of habit.

Anyway, the system incompatibility seems to have gone away with the latest git
pull.  I don't know if it was an actual incompatibility, or if it was caused by
dub not liking it when I interrupt it with ctrl-C and then try to rebuild again
afterwards, or something like that.  (I know it shouldn't be a problem, but
sometimes these things do happen.)

Basically, I would like to have the option of being able to build docs without
network access.
