That is correct, gnome-config is not required. It may be referenced,
but it is a legacy (i.e. GNOME 1.4) component which most likely will not
be installed on modern systems. If the code which references
gnome-config is executed, that means the required pkg-config (i.e. .pc)
file could not be found. If that pkg-config file is a hard requirement
of a given piece of software, then that likely points to a missing or
corrupt package dependency.
