I do have time-compat installed:

pacman -Q haskell-time-compat 
haskell-time-compat 1.9.5-47

Is that some sort of compatibility issue? Distro: Arch Linux x86_64, rolling

I have built hsemail successfully with time-compat version 1.9.5. I don't see the error message you reported. Looking at the exact message, however, it looks like

There are files missing in the ‘time-compat-1.9.5’ package, try running 'ghc-pkg check'.

is a system-level error, not an actual compiler error. Is it possible that your installation has been corrupted in some way? Could you please run ghc-pkg check? Also, it might be a good idea to re-install time-compat from scratch to make sure all files that it's supposed to contain are actually there.

Thank you, turns out that incorrect configure parameters were passed in PKGBUILD . Since the package was disowned I adopted and fixed it so that it compiles. Truth be told I have zero knowledge how haskell compilation works - it was more like trial & error.
