Forwarding my message to meld-list, since it continues the discussion about
another non-standard-prefix meld install.
This message contains investigation&resolution for the exception
>>>>>> gi.require_version("Gtk", "3.0")
>>>>>> AttributeError: 'module' object has no attribute 'require_version'
It was name conflict of pygobject with unrelated gi package
(pypi.python.org/pypi/gi/1.2)
(typical sending to both list and Niraj Pandey fails for some reason, in such
case only list receives my mail).
