Subject: Problem with "Daemon not connected"

I am having a problem with a script and hope someone here can help.

I have a Ruby script that includes an "open" method call to create a
subprocess and return a string.  Shown here is a much simplified
version where I can recreate the problem.

$f = File.open("/tmp/foo.log", "a")
#cmdline = "|ls -l"
cmdline = "|/opt/localname/bar ..."
s = open(cmdline)
s.each do |line|
  $f.print line
done

When this script is executed from the command line shell the "open"
method succeeds for the /opt/localname/bar program.

However, when the script is executed from within a shell script the
method fails.

Instead of printing the expected results the message "Daemon not
connected" is printed.

The "ls -l" command works in either situation.  

I have reviewed the environment variables and there does not seem to
be anything relevant there.  Any thoughts?  Pointing out a stupid
mistake would be great!
