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: Warning: g_object_ref: assertion 'G_IS_OBJECT (object)' failed icon = self.render_icon(Gtk.STOCK_EXECUTE, Gtk.IconSize.BUTTON) --------------------------------------------------------------------------- TypeError Traceback (most recent call last) /usr/local/lib/python2.7/site-packages/graph_tool/draw/gtk_draw.pyc in draw(self, da, cr) 492 if self.surface_callback is not None: 493 icon = self.render_icon(Gtk.STOCK_EXECUTE, Gtk.IconSize.BUTTON) --> 494 Gdk.cairo_set_source_pixbuf(cr, icon, 10, 10) 495 cr.paint() 496

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 -- Tiago de Paula Peixoto <tiago@skewed.de>
