I had the same problem.  Running dot -c would hang forever on my desktop
with x11/nvidia-driver installed, but would work fine on other systems.
 Enabling the NVTHREADS option in graphics/graphviz seems to have solved
this problem for me.

As there seem to be no side effects with enabling the option on
non-NVIDIA systems, I just added this to Poudriere's make.conf:

  graphviz_SET+=NVTHREADS
