apecs-gloss-0.2.2 fails to build in Stackage Nightly

[juhp]

While trying to build Stackage Nightly I ran into:

Is this caused by newer apecs-physics?

Thanks for reporting. Strange, it definitely looks like it was caused by the apecs-physics update, but I can't seem to replicate (nightly-2019-08-12), what command are you using?

[juhp]

Ah I wasn't clear I was trying to produce the next Stackage Nightly.

To reproduce, you should use your latest versions. :)

[jonascarpay]

Yeah I realized, what's weird is that neither CI not my own builds have trouble with it, even though it's using the same configuration as far as I can tell.

I did not see #50 also changed apecs-gloss, I bumped and uploaded it to hackage.
