Thanks Seth,

I will try the latter and let you know. I had also downloaded gcc 4.0.3 from
the same site and thought that it was the same compiler as was used for the
graphviz. I will do once more and let you know...if this does not work, I
shall venture into the realm of building graphviz from source and let you
know how that turns out.

Thanks again,
--Tony
