It's a Stackage LTS and then Hackage for everything else, to be more precise, no?

I'm trying to fix a broken package named ffmpeg-light. Here is what I have so far:

ffmpeg-light = lib.pipe hprev.ffmpeg-light [
  unmarkBroken
  doJailbreak
  (addSetupDepend prev.ffmpeg-full.lib)
  (drv: drv.overrideAttrs (attrs: { dontWrapQtApps = true; }))
];

However, the ffmpeg libs are still not found:

Here's what the cabal wants:

  pkgconfig-depends:   libavutil, libavformat, libavcodec, libswscale, libavdevice,
                       libswresample

Here's what ffmpeg-full.dev has:

Heya, a while ago I wrote a program that uses the punycode package, which is marked as broken in nixpkgs. I'm trying to figure out why but have gotten nowhere, any suggestions?

Have you looked for a "broken.yaml" file in nixpkgs and read the line in the corresponding comment?

Hey all! I'm routinely getting strange "missing dependencies" errors when trying to build with cabal on my NixOS machine. Never happens on non-NixOS. I must be missing something? E.g.:

Failed to build unix-2.8.6.0. The failure occurred during the configure step.

):

Encountered missing or private dependencies:

Are you trying to override the unix package?

Boot libraries have special handling and cannot be overridden in the usual way.
For example:

nix-repl> haskellPackages.unix
null
