[Sugar-devel] Working text to speech example needed

[Jerry Vonau]

Think you might be missing the pygobject2 rpm, from 'dnf info pygobject2'
Description : The pygobject2 package provides a convenient wrapper for the
GObject library
            : for use in Python programs.

Hope it helps and/or works,

Jerry
