povray @3.7.0.unofficial no image display while rendering

[fritz.ganter@…]

Since Mac OS X 10.11 El Capitan povray shows no preview image while rendering. I get the following message in console:

20.12.15 01:03:24,849 povray[8828]: WARNING: The Gestalt selector gestaltSystemVersion is returning 10.9.2 instead of 10.11.2. This is not a bug in Gestalt -- it is a documented limitation. Use NSProcessInfo's operatingSystemVersion property to get correct system version number.

We're not doing anything special in the povray port to cause that. You should report the problem to the developers of povray.
