Comment (by ryandesign):

 Replying to [comment:1 jmroot]:
 > It appears that ghc uses `utimensat` in its public headers, which means
 those headers can't be used without that function being available. As
 you've discovered, it's only available on macOS 10.13 and later. There is
 an implementation in legacysupport, but that means that all ghc dependents
 (or at least all those that include this particular header) are obliged to
 use legacysupport, which is unfortunate.

 It's the ghc-filesystem port, not the ghc port, so that's a much smaller
 set of affected ports. I'll add legacysupport.
