This re-affirms my suggestion about some type of a popup.  People
typically look at the help for info on what a particular applet may
do, not what its requirements are.  It would be better to have a popup
to alert the user that "Hey you either need to enable the BB
supplemental binaries required for this to work, or supply your own -
see the help for details."  Again, I didn't look at the help because I
knew what the commands did.
