Hi Rainer,

There doesn't appear to be an easy way to convince
plugins/GraphLayout/configure to ignore an already-installed version
of graphviz, and I don't see any patches for ggobi that enable it to
support new versions of graphviz.

At this point, I would add a post-configure target to the port
Makefile and use it to patch plugins/GraphLayout/Makefile and
plugins/GraphLayout/config.h to remove support for libgvc.  I did that
manually, and I was able to build the plugin by hand with graphviz
still installed.

Hope that helps,
Greg
