The build should work with a locally installed Graphviz (`dot`) picked up from the environment, but as has been shown here, the output from different versions of Graphviz can vary. So yes, the build output can vary depending on the versions of tools used in the build.

To guarantee that builds from Oracle have a consistent output, we use defined versions of various tools, such as Graphviz, and for transparency we provide the scripts used to create those tool bundles in the make/devkit dir in the source tree, so that anyone who wants to know what we use can easily find out and replicate if desired.
