This Apple documentation seems relevant:

"Carbon Core, a subframework of the Core Services umbrella framework, contains the programming interfaces of many legacy Carbon managers, in addition to various utilities. In OS X v10.8, most of these interfaces are deprecated. "

Especially the section "Components" https://developer.apple.com/library/content/releasenotes/General/CarbonCoreDeprecations/index.html#//apple_ref/doc/uid/TP40012224-CH1-SW6

"If you need to find and open audio units and audio codecs in your app, use Audio Component Services instead of the Component Manager (for more information, see Audio Component Services Reference)."

When I invoke the freeciv-gtk2 client from the command line, I see a warning message. The initial Freeciv window still appears.

% freeciv-gtk2
2017-03-02 16:30:54.886 freeciv-gtk2[99591:5959094] 16:30:54.886 WARNING: 140: This application, or a library it uses, is using the deprecated Carbon Component Manager for hosting Audio Units. Support for this will be removed in a future release. Also, this makes the host incompatible with version 3 audio units. Please transition to the API's in AudioComponent.h.

Freeciv-gtk2 2.0 client, freeciv 2.5.5, installed from MacPorts.
Observed on Mac OS X 10.11.6 "El Capitan".
When running a similar version of the freeciv-gtk2 client v2.5.5 on this same computer, when it still had Mac OS X 10.10.5, this message did not appear.
