I assume that it's not failing on this:

    if script -S /bin/sh 'echo OK' /dev/null 2>&1 | egrep 'OK' >/dev/null;

because I don't think that MacOS X script supports -S.

Does removing the output redirection to /dev/null on lines61 help?  If
so, that's wierd but we could deal with it. 

I assume that it hangs on the following  line?

    run_without_input 'if test -t 0  -a  -t 1  -a  -t 2; then echo tty; fi'

Maybe run that in the background, sleep for a second, then see if the process
is still running?  If so, kill it and test_skip?
