Help getting Nautilus running under MacPorts I have been trying to run Nautilus on OS X 10.6.8 without any luck. First, I installed MacPorts, then installed Nautilus. However when I try to run it from the command line, I am getting an error. I came to this thread and followed the instructions given. However I am still getting this error:

(nautilus:27170): Gtk-WARNING **: Locale not supported by C library.
    Using the fallback 'C' locale.
Xlib:  extension "RANDR" missing on display "/tmp/launch-42nv45/org.x:0".

And then X11 stops unexpectedly. Can anybody tell me how to solve this?
This sounds like a problem in X11 itself. To find the real issue with X11, you would have to take a look at the generated crash reports. You will find these within the application Console at "Diagnostic Reports".

As a workaround, you could try to use XQuartz instead, which is a package providing an usually more up-to-date version of the X server for Mac OS X.
