This sounds very similar to a problem reported with Devel::SmallProf at A substitute for Devel::Smallprof?. That too was a profiling module, reported the "No DB::DB" problem and involved Time::HiRes.

I posted a workaround patch for SmallProf which might point a way to work around the problem with GraphVizProf.pm and the author of the module released a new version which fixed it properly.

I couldn't get to CPAN to check if this might be a similar problem with GraphVizProf, I'm not sure why, but I'll update if/when I do manage to get there.

If I understand your problem, I can solve it! Of course, the same can be said for you.
