Oh, BTW - welcome back, Lamar!
AOLserver's also dependent on libxml2. OpenACS 4 no longer requires PL/Tcl so we don't need that any more.
How should we handle optional elements, like ImageMagik and Graphviz? I would assume we shouldn't force folks to have these available in order to install the basic system, but we should document which packages require them (workflow for Graphviz, the photo packages require ImageMagik)
