I run raspbian, a Debian derivative to support armv6 hardfloat, I
recently updated ghc in raspbian bookworm to 9.0.2-4+rpi1 merging
our local changes (mainly changing the compiler defaults) with the
9.0.2-4 version that had just landed in Debian bookworm.
Unfortunately after doing so it seems all haskell library packages
are failing to build with errors like:
[1 of 1] Compiling Main ( Setup.hs, Setup.o )
<no location info>: error:
Warning: Couldn't figure out LLVM version!
Make sure you have installed LLVM between [10 and 14)
ghc: could not execute: opt

Has anyone seen this issue before? or have any suggestions on how
to debug it?
