These look primarily like the busywork of bounds bumps, is that right? Perhaps due to some packages not building under 9.6 on some architectures?

There are some toolchain issues too:

- macOS stopped working with brew provided toolchain (that is supposed to work, although some sources say you should use the “system toolchain”)
- FreeBSD bindist (which I built myself) fails with: `libHSghc-9.6.5.a: error adding symbols: malformed archive`

The other seem mainly to do with streamly, which is why I’m now considering to move away from it: [Move away from streamly? · Issue #1051 · haskell/ghcup-hs · GitHub](https://github.com/haskell/ghcup-hs/issues/1051)

The issue is the toolchain is that it mixes a clang and gcc based toolchain, not that it’s provided by brew or otherwise.
