You pointed me in the right direction. The funky graphviz directory is being sought by the dot program that was compiled as part of the GraphViz binary created by pixelglow folks http://www.pixelglow.com/graphviz. Both you and jasonk further pointed me in the right direction by prodding me to ditch ActiveState, and roll my own. Its gonna be painful, but trial by fire and all that... so, I am doing that as we speak, and the compiler is chugging away in the background.

Its just all those dependencies... looking at Graphviz (the program, not the perl module), that dang package has sixty zillion packages it depends on, and one or more are bound to make me want to reach for Zantac.
