It has a constraint on an old version of gtk, so doesn't build and seems
abandoned (no release since 2017, copyright notice year range ends with
2010).
A few libraries published by https://github.com/typeclasses/ have the issue
that they have a test suite with its Main module in hegehog.hs. On darwin
GHC can't distinguish between Hedgehog.hs and hedgehog.hs due to the case
insensitive file system and will raise an issue about this.
Interestingly SDL-image exhibits both the problems of SDL-mixer and SDL-ttf
have. How the respective fixes we apply here as well work is explained in
1a68ebf98573291fc4a8d8e7b35ea2e74a0d6665 and
2a8105fc58644307007f326de25b357d216d3ad7.
SDL-mixer's configure script makes some darwin specific assumptions about
the layout of the SDL libraries which don't hold up with the way they are
packaged in nixpkgs. Since the way we are doing this on other platforms
works with the configure script and doesn't significantly differ from the
situation on darwin, we can just replace a string in a string comparison
to ensure the non-darwin code path is taken.
SDL_main.h which is included from SDL_ttf.h contains a #define which redefines
main to SDL_main. This has to do with the way SDL binaries are linked and
executed on darwin which is explained here [1]. However this is bad news for
hsc2hs intermediate C sources which in this case only to gather version
information from the headers and not to run a full SDL application.
Thus compilation would fail due to this issue which we can avoid by redefining
main to main again after including the header.

ats-format has a custom Setup.hs which does the following using cli-setup:
* Add ~/.local/share/man to $MANPATH by editing shell configurations in $HOME.
* Install a man page into ~/.local/share
* Install a shell completion by editing shell configurations in $HOME.
We had a workaround to keep this from failing the build in the nix sandbox, but
this seemingly broke on darwin. To fix this once and forall, we force the use
of only `defaultMain` in Setup.hs and install the man page manually.
Additionally we generate completions and remove unnecessary extra references
from the closure.
We employ a workaround for a GHC bug [1] which has been adopted by both
Debian and Fedora for a eerily similar problem on ppc64le. Hopefully
this fixes our aarch64 issue as well (untested so far). -O0 is not
ideal, but compilation with -fllvm fails when linking (due to an
invalid relocation and passing -fPIC wasn't enough to fix it), so
we're stuck with this for now.

Test suite depends on an old version of base16-bytestring (but has not
set up constraints for it). Can't be bothered to add an old version of
it, let's just disable the test suite for now. This should fix itself
sooner or later.
