Forgot to add that my current workaround is to compile with "-static
-package-env=-" i.e.
ghc -static -package-env=- -prof -fprof-auto hello.hs
Adding just -package-env=- i.e. gives me the same error as compiling
without it.
ghc -package-env=- -prof -fprof-auto hello.hs

Perhaps you haven't installed the "p_dyn" libraries for package
‘base-4.18.0.0’?
Use -v (or `:set -v` in ghci) to see a list of the files searched for.

Adding just -static gives
ghc -static -prof -fprof-auto hello.hs

I can't find any doc saying that -static is required for profiling on the
Mac but perhaps that is the case?

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
