ghc-9.10.0.20240313 (alpha1) does not install on macOS

Issue #21506 (closed) is back for 9.10-alpha1. Same description, same symptoms, probably same cure.

Spelling it out:

macOS Monterey 12.7.1
download https://downloads.haskell.org/~ghc/9.10.0.20240313/ghc-9.10.0.20240313-x86_64-apple-darwin.tar.xz
tar xf ...; cd ghc-...; ./configure
Produces pop-ups stating that "libHS... was blocked, not from an identified developer"

Here is some detailed error, but this is probably not interesting, since it is really a reprise of #21506 (closed) only:

I would assume it is a packaging error.
