After playing around a bit more, and looking at your code a bit more
carefully, now I'm wondering what's the correct way to specify a custom
path to DMD?

It seems that specifying DC='/path/to/dmd' doesn't work properly,
because the tool tries to auto-detect gdmd and dmd, and if gdmd is found
first, it will assume a gdc installation and attempt to link with
-lgphobos2.  Thence, changing DC manually does not change this
assumption, and as a result things will break when it tries to link dmd
objects with libgphobos2 instead of libphobos2.
