Xlib problem with gv and ggv on OS X 10.5.6

[joe@…]

gv builds fine, but when I try to launch it I get the following error message:

Xlib:  extension "Generic Event Extension" missing on display "/tmp/launch-FgEo1k/:0".
Error: attempt to add non-widget child "fileButton" to parent "control" which supports only widgets

ggv also builds fine, but I get a similar error message when I try to launch it:

Xlib:  extension "Generic Event Extension" missing on display "/tmp/launch-FgEo1k/:0".
Xlib:  extension "RANDR" missing on display "/tmp/launch-FgEo1k/:0".
Xlib:  extension "Generic Event Extension" missing on display "/tmp/launch-FgEo1k/:0".
Xlib:  extension "Generic Event Extension" missing on display "/tmp/launch-FgEo1k/:0".
Xlib:  extension "Generic Event Extension" missing on display "/tmp/launch-FgEo1k/:0".

I don't actually use gv and I hadn't heard of ggv so I have no input on this problem. I recommend you ask the developers of gv and ggv or the macports-users mailing list. If you discover something that needs to be changed in the gv or ggv ports to fix this problem, please mention it here so I can take care of it.

Regarding the RANDR message, do you have the port xorg-libXrandr installed and activated?

The messages about missing extensions are harmless.

For me, gv refuses to start with the above message. I wouldn't consider that harmless. I'm not using gv that oven, but still this is a bit annoying. #18751 talks about another app (gnucash) crashing with a similar message, could that be related?

While googling i found  this, which talks about the problem stemming from "when you have a XGE-enabled xlib connecting to an non-XGE enabled x server". Could this be the problem here? Is the macports libx11 built with some extensions that the Apple X11 server does not understand?

The "attempt to add non-widget child" error is not harmless, but that's not a message about a missing extension.

Current versions of both seem to work fine.
