Bingo!!!!

Actually, about an hour ago, thanks to Carlos Cantu's suggestions, I
discovered when I ported my host application from Delphi 7 to Delphi 2009
that the setting to make it use runtime packages was lost in the shuffle.
Once I turned runtime packages back on it was able to load the packages
dynamically again. I was assuming that aspect survived the port.
