RDoc: .png files are empty

Hi, I’m trying out RDoc for the first time. When I run ‘rdoc -d’ in the
rdoc directory, everything seems ok, except that the .png files in
doc/dot are empty, so of course no lovely diagrams in the browser. My
dot installation seems to be ok (one of the Tk samples that comes with
dot, tcldot/demo/doted, runs fine). What else should I check?

What version of graphviz?
I had problems with an older version segfaulting while processing the dot
files (although it did work with various other things), graphviz 1.8.9
seems to be working OK.

versions above 1.8.2 seem do not work.
I experiences some problems with v1.8.4 last time I tried.
But the v1.8.2 works well

$ rpm -qa | grep graphviz
graphviz-1.8.5-0

(I tried building from source first, but had undefined references to
functions in libiconv.)

I didn’t get any error messages from rdoc. The output ends with:

Generating HTML…
Diagrams: …

Would it help to look at the -D output?

If someone could pin down the features that RDoc is using that are
causing problems, I’d be happy to fix it.

Thanks
