Wow, you upgraded the whole machine! I'm impressed.
You are now running basically the same setup I have used successfully.
This definitely should work. When it hangs, did you try C-c C-c?
There are other interrupts that you can send from the Signals menu,
but usually Break (C-c C-c) is what you want for a hang.
Also, look at the SAS shell script that ESS uses. It can be found
in PREFIX/share/emacs/etc/ess/ess-sas-sh-command It should have
+rx privileges for you. You can test it from the command line...
$ PREFIX/share/emacs/etc/ess/ess-sas-sh-command /dev/stdout /dev/stderr -stdio -noovp
