Hello,

The `dub` package cannot be installed on an up-to-date Guix System. I am
attaching the failed build log, although honestly I couldn't make much
from it.

This of course has implications such as `dub-build-system` not working...

Best wishes,
Hugo

This probably went unnoticed because we don't actually _have_ any
Dub-based packages. Anyway, from that log:

Toggle quote (6 lines)

Something something templates, something something throwable, something
something optional type, something something second-system syndrome.
Seems likely to me that our Dub is too old for our ldmd2. I'll send a
patch to update it.
