Please open a Terminal.app window and type the following lines:

   bash ~$ echo ${GNUHELP} ${GNUPLOT_PS_DIR} ${GNUPLOT_DRIVER_DIR}
   bash ~$ echo ${GNUTERM} ${DISPLAY}

Then please send the output of this lines.

As a second example you can start up Gnuplot like this:

   bash ~$ GNUTERM=x11 /Applications/Gnuplot.app/Contents/Resources/bin/gnuplot

this opens up X11.app automatically before and then launches Gnuplot, does this 
work?
