Comment (by john@…):

 Hi Ryan,

 I have xorg-server.  I just reinstalled that from MacPorts.  It may not
 have been installed before.  Now after restarting, the error is totally
 different.

 I'm not sure if / how to set my Display variable to that server.  I may
 have missed a step here.  Now that xorg-server is installed, what else do
 I need to do?

 Thanks so much!
