Trac installation issue with dot

Couldn’t find a suitable admin contact on Haiku’s Trac, so I post it here…
When trying to show the dependency graph of a ticket via the “depgraph” link on a ticket, I get an error page saying thus:

Path to dot executable is invalid: dot

Hi!

First time I read about a “depgraph” link… and I can’t find that at Trac at all. Or am I blind… ? :sunglasses:
