Well, I know the reason it cannot build with base-4.9.0.0: My library is
fully compatible with base (>=4.6 && <4.10), but it depends on the Gloss
library (>=1.7 && <1.10). I cannot use Gloss 1.10, because Gloss 1.10
has a breaking API change on one of the Gloss functions I use in my
library, which I could only get around if I used a lot of conditional
code, which I haven't done yet. However, only Gloss 1.10.* is compatible
with base-4.9.0.0.

Hackage, it is seems, will only try building with base-4.9.0.0, rather
than reverting to an earlier version and compiler. The package builds
just fine on my system, using an earlier base and compiler. So, I guess
the question is, do I have to further restrict the dependencies of my
library (to exclude 4.9.0.0) just because one of my dependencies cannot
handle that version?
