That's what I have been afraid of :(

For me it would be ok to disable the facility to use external graphviz

Would you agree to share your patch, so that I could use it in the port?
There was no attached patch ;)

You helped me a lot. I had been looking for some time now to find a

Many thanks again,
Rainer
