make more sense to add the check to the ATLAS spkg instead of `prereq`?
Its already there and provides info.
I'm ok to not check anything in prereq and let the ATLAS spkg do the job
(although the user might say "hey it passed prereq and now its asking for
something more to be installed so much later!!!").
(And I just uploaded a new patch without redundant SunOS check.)
