Ruby 3.1.2 broken when using ca-derivations

[j-baker]

Describe the bug

I'm aware that ca-derivations is experimental. I'm finding that on 23.11, Ruby does not compile with ca-derivations enabled.

Steps To Reproduce

Steps to reproduce the behavior: Build ruby with nixpkgs.config.contentAddressedByDefault = true. Get

error: build of '/nix/store/dpbvdh8pflzhkwkmjq92zmy85awq4jaw-ruby-3.1.4.drv' on 'ssh-ng://helcache@i-01bfd4ac504a8b1f0.eu-west-1.compute.internal' failed: derivation contains an illegal reference specifier '/0i99q8f7j8dv45qvbx1issri3v1w08z2mkhn5pv23i626zy2r029'

in return.

Expected behavior

Either Ruby has CAD disabled or passes.

Would you mind testing whether #258705 fixes the Ruby ca-derivation?

jfc is it totally deranged how this is meant to be tested
pillowtrucker/computer-nixos@4afe14d I /think/ I figured out how to overlay this, because naturally the normal ruby = coolpackages.ruby didn't work. It's building now and I'll let you know in the morning if it worked, because it is the last 500+ packages that I have to rebuild to enable contentAddressedByDefault, but probably yes, since it didn't immediately implode.

works for me
