Thanks Tiago.  Using the Macports install was the very first thing I tried, I’m rather committed to Homebrew through other packages.  The two of them don’t play nicely together, and I ended up breaking a lot of other things.  I might look into trying to get them to cooperate if I can’t get a fix for GTK.

Cheers,

Charlie

Hi again Tiago!

I tried editing the Homebrew formula for librsvg to obtain the latest
version and enable introspection, and sure enough I can now produce an
interactive graph!  Hooray!  I've posted the issue on the Homebrew github
page that you referred.

BUT: now I have a different problem.  In my beautiful interactive graphs,
the second node I select infallibly triggers a fatal error that kills the
kernel.  Here it is:


/usr/local/lib/python2.7/site-packages/graph_tool/draw/gtk_draw.py:493:

Any ideas?  Thanks!

Well, this is obviously a Gtk bug, since it is failing to render a stock
icon. You should also report this to the homebrew people.

(Alternatively, you may try Macports, where it is reported to work)

Best,
Tiago
