If you have built R from source, then you will probably have the best
luck building graphviz from source as well to ensure that R and
graphviz use the same compilers.  Building graphviz from source may be
non-trivial as it probably requires various non-default devel
tools/libs.

So one thing to try is to build the latest graphviz 2.12 from source.

Or you can download and install the gcc that was (presumably) used to
build the graphviz 2.8 binary package and rebuild R with that.  I
_think_ that would get things going as well.
