I suspect that you have solved this problem already, but here is
the line that you meant to type, anyway.

	rsh spica "ps -l | awk '{ print \$4}'"

Your problem was in your understanding of the local shell and how it
handles quotes and double quotes. You assumed that because the $4 was
inside single quotes the local shell would leave it alone, however, the
single quotes were surrounded by double quotes and lost any special meaning.
Try this example:

	echo "'$0'"

The $0 is expanded by /bin/sh because the single quotes are quoted.
