Failure of plot with -T X option

[sugar@…]

I just installed the plotutils. The plot executable works correctly with -T ps, -T png and -T gif options. However, which I use the -T X option to display an X window I receive an error message that reads:

libplot: ignoring request to create plotter of unknown type plot: error: could not create plot device

I believe that X11 is properly installed, and would appreciate any advice you have.

Did you install plotutils with the x11 variant (sudo port install plotutils +x11)? By default, X11 support isn't included with it.

I reinstalled the plotutils with the +x11 variant. That fixed my problem. Thanks very much for your help.
