• Built on platform(s)
  • NixOS
  • macOS
  • other Linux distributions
• Tested via one or more NixOS test(s) if existing and applicable for the change (look inside nixos/tests)

@svmhdvn When you send these PRs, can you make sure to run the following types of ofborg commands? This makes it easy for someone to just quickly check if the packages are all still building:

@GrahamcOfBorg build haskellPackages.classy-prelude-yesod
@GrahamcOfBorg build haskellPackages.rank2classes
@GrahamcOfBorg build haskellPackages.HaTeX

(The aarch64 and darwin builders are sometimes not too reliable, so I'm basically looking at the x86_64 Linux ones)

Sure, I’ll do that on the other PRs, thanks for the info.

Looks like these three are building on Linux. Thanks!
