ldc 1.42 beta 1 was released today with support for llvm 21:
https://github.com/ldc-developers/ldc/releases

Alternatively, I think we could build ldc with llvm 19 temporarily to
give us more time. (I did this in Ubuntu 26.04 LTS.)

Thank you,

Matthias Klumpp,

ldc 1.42 was released. Do you want to try packaging it and switching
it to llvm 21?

This was done, and the FTBFS is fixed. Let's lower this. It'd still be nice to
switch to LLVM 21 or 22, since LLVM 19 may be removed from forky.

Cheers,
