What are the dependencies for Graphviz Plugin?

Better documentation of this would help installers like myself ...

I have cmd_path = /usr/share/graphviz on an ubuntu 6.06 system. I'm getting:

Graphviz macro processor has detected an error. Please fix the problem before continuing.

The rsvg program is set to <b>/usr/share/graphviz/rsvg</b> but that path does not exist.

Well, I've tried installing graphviz and librsvg2-bin. I've set the rsvg_path, and tried various graphviz.*/* invocations via the wiki. It's still failing to work in various ways, not to mention the fact that installing graphviz and librsvg2-bin loads up the system with a lot of packages I don't want or need.

Here's one failure:

I'm a little disheartened about this plugin ATM...

Do: apt-get install librsvg2-bin

then "which rsvg you should display

/usr/bin/rsvg
