What do you get for gcc --version?
If you don't see 3.3 then try:
sudo gcc_select 3.3
And rerun the install.

This is not a supported graphviz version.  It _may_ work and the
cc_dynamic issue is unlikely to be related to this, but if things
don't work after install, well, send us reports but be patient.

And this is quite odd because it looks like it *is* finding a
dotneato-config which suggests you are picking up an older version of
graphviz located in /opt/local/...
