X11/Gnuplot Broken.

[WP Becker]

Greetings! Newbie list member here.

I recently upgraded my Mac to OS X 10.6.5. The upgrade appeared to go 
flawlessly, as usual.

However, now the X11/Gnuplot interface is broken. I receive the following 
nastiness when I perform a simple plot from the Octave command line.

Octave and Gnuplot are located in /Applications. X11.app is located in 
/Applications/Utilities.

Using the terminal app, the /usr directory contains:

drwxr-xr-x     8 root  wheel    272 Sep 15  2009 X11
lrwxr-xr-x     1 root  wheel      3 Sep 15  2009 X11R6 -> X11
drwxr-xr-x     3 root  wheel    102 Jan  9  2009 X11R6 1


Any help or suggestions would be appreciated.

Thanks!
