Is anybody on 9.6.1 having problems profiling on a Mac? As I reported in
https://gitlab.haskell.org/ghc/ghc/-/issues/23211

ghc -prof -fprof-auto hello.hs

where the file hello.hs consists of the line:

main = print "hello"

gets the error:

Could not find module ‘Prelude’

 Perhaps you haven't installed the "p_dyn" libraries for package
‘base-4.18.0.0’?


It seems to me like a regression of the closed bug
https://gitlab.haskell.org/ghc/ghc/-/issues/20707.

Thanks
George
