Unfortunately ghc doesn't work after installing 9.4.1 on my Mac. Does it
work for others?

After the install finishes when I do the following:

$ ghc --version
bash: /usr/local/bin/ghc: Permission denied
$ sudo chmod +x /usr/local/bin/ghc
$ghc --version
/usr/local/bin/ghc: line 1: exec: : not found
$ cat /usr/local/bin/ghc
exec "$executablename" -B"$libdir" ${1+"$@"}
$ cat /usr/local/bin/ghc-9.4.1

exec "$executablename" -B"$libdir" ${1+"$@"}
