RDOC and dot on mac

Rails
1

All,
This is probably a bit more of a mac question, but here goes.
(Admission: I
posted this to ruby-talk as well…)

I am trying to use rdoc -d to generate class diagrams on a mac running
Tiger
(OS X 10.4) for a rails app. I managed to get dot installed, but now am
running into problems with dot looking for libraries that either do not
exist or are apparently in the wrong place. I probably made things worse
by
trying (at various times) both Darwin ports and i-installer. Can anyone
point me to instructions on getting this working?

BTW, the current error I am getting is

dyld: Library not loaded: /Local/DarwinPorts/lib/libpng.3.dylib
Referenced from: /usr/local/bin/dot
Reason: image not found

TIA,
Keith

This would be kinda hackish, but you could download Graphviz[1] and
use the prebuilt dot buried inside of the .app package.[2]

Or maybe you just need Graphviz. I find quite a bit handier,
especially for large graphs.

  1. pixelglow | graphviz
  2. ./Graphviz.app/Contents/MacOS/dot

Corey,
Thanks - I had actually tried that, but could not figure out how to use
the dot that is embedded. How do you tell rdoc to use that one?

Duh- got it working by creating a sym link to the dot file in the
graphviz directory. Guess I am still doing something not quite right,
since the output appears to be many diagrams, each of one source file. I
am looking for an overall class diagram.
