Hmm .. http://www.graphviz.org/content/output-formats#dpdf

Is it a problem of the GraphViz version?

See http://www.graphviz.org/News.php ..

"""New Release 2.32 (1 August 2013)

... In addition, if the poppler library is available, Graphviz
can now use PDF files as images."""

I suppose that 2.32 is in your distro .. it's from 2013

It seems, that the graphiz homepage is not up to date. I found
the repo at github. There is a issue about PDF

https://github.com/ellson/graphviz/issues/1180

So I guess graphviz is compiled without HAVE_PANGOCAIRO in your
distros?
