------------------------------+--------------------------------
 After installing MacPorts I found a new line in .bashrc setting the
 $DISPLAY variable to :0. This is highly problematic because the Xorg
 server sometimes creates a new display port (e.g. :1). In this case, X
 applications will not be able to work because the DISPLAY was set to :0
 and an annoying "unable to open display at :0" error appears. MacPort
 should not set the DISPLAY variable to :0. If it is necessary to set it
 then the port needs to be set dynamically, depending on the used display
 port of the currently running X server.
