This only appears to be affecting Darwin builds. Still appears to be building fine on Linux according to hydra.

Thanks for reporting this. Unfortunetely Darwin build issues are a bit harder for me to debug but I will try look what this could be about. If there is anyone else willing to look into this please do.

EDIT: From the log it looks like GHC fails to build. So this one will be up to haskell packages folks to address.

A possible workaround could be to override the used stdenv to use clang < 18 as cc. As the linked issue describes, I've been trying to figure out the cause of the issue over christmas, but so far to no avail. Maybe the upstream developers will have some input in the coming days.
