As has already been posted, port_cutleaves is probably a better
solution.  But here's the correct xargs syntax anyway.

port installed | sed 's/ (active)//g;s/@.*//;s/ //g' | gxargs -d "\n"
-n1 port dependents

Note that I used gxargs, provided by findutils, as Apple provided
xargs does not understand the "-d" flag to change the delimeter.
Also, "-0" would be used to tell xargs that records are separated by a
null character.  This usually only occurs with output from "find
-print0".
I also stripped a bit more from the "port installed" output.
