Can you post the output of R CMD INSTALL Rgraphviz_x.y.z.tar.gz
Rgraphviz should be detecting pkg-config.

Depending on where/how graphviz was installed, you may need to add a
path to PKG_CONFIG_PATH.  Perhaps something similar to:

export PKG_CONFIG_PATH=/usr/local/lib/graphviz/pkgconfig

If pkg-config and graphviz are setup correctly, then the following
should work:

  pkg-config libgvc --modversion
  2.6
