elm package is broken

[abbec]

Describe the bug
The elm package fails to build because of snap-server failing to build

To Reproduce

nix-env -iA nixpkgs.elmPackages.elm

src/Snap/Internal/Http/Server/TLS.hs:108:14: error:
    Not in scope: ‘Socket.bindSocket’
    Perhaps you meant one of these:
      ‘Socket.fdSocket’ (imported from Network.Socket),
      ‘Socket.mkSocket’ (imported from Network.Socket),
      ‘Socket.withFdSocket’ (imported from Network.Socket)
    Module ‘Network.Socket’ does not export ‘bindSocket’.

108 |              Socket.bindSocket sock addr
    |              ^^^^^^^^^^^^^^^^^

builder for '/nix/store/71cdi2kbihkqd4f3p4n2kmz31i3wk2za-snap-server-1.1.1.1.drv' failed with exit code 1

Expected behavior
Elm is installed.

Fixed in #75882 (although it hasn't been merged into master just yet).

[abbec]

Cool! I will close this then? Or should I wait until it is merged in?

[cdepillabout]

@abbec It will eventually be merged, so I'll go ahead and close this.

If you (or anyone else) want to use this now, you can currently get it from the haskell-updates branch.
