Error installing 5.1.1: zstd/lib/libzstd.so: undefined reference to `pthread_create@GLIBC_2.34'

Hi! I'm coming back to OCaml after a few years and tried to install 5.1.1, and I hit this issue.

I'm on ubuntu using linuxbrew/homebrew, which I used to install opam.

Using opam then to create a switch for 5.1.1 breaks, and I think it is related to this issue https://github.com/ocaml/ocaml/issues/12562.

~ → brew info opam
==> opam: stable 2.1.5 (bottled), HEAD

~ → opam switch create 5.1.1

I've switched back to 4.X which installs without issues as I reacquaint myself with the language.

I just tried, and I get the same error.

The error seems to mention glibc@2.34, but I have → ldd --version # ldd (GNU libc) 2.35. I'm not sure if that is exactly the issue, from what I see brew's opam does depend on glibc.
