graphviz @2.49.3_0 +lua: "graphviz violates the layout of the ports-filesystems!", preventing activation

[outis]

While working on ticket #64106, I came across an error while activating graphviz when including the +lua variant:

$ sudo port install graphviz +guile+java+pangocairo+perl+python27+poppler+rsvg+ruby+smyrna+tcl+x11

After dropping +lua, an install generated no warning and no error.
