rednotebook @1.2.0_1: cannot find symbol "_xcb_str_sizeof"

[ronank@…]

I am trying to run rednotebook on Mac OS X. It took some effort to install it - there were problems building avahi. I eventually got that to build by not including gtk but I think that may now be causing issues.

I have installed rednotebook but it will not launch. The error message is:

rednotebook: update to version 2.3, dependencies

Previously a dependent of py27-webkitgtk, it now depends
on python36, gtk3 and webkit2-gtk using gobject introspection.
