[Sunhelp] gnuplot library problem

[Tom Jones]

I just installed gnuplot3.5 on Solaris 2.6

When I invoke gnuplot I get the following error regarding a missing library:
/usr/local/bin/gnuplot: fatal: libX11.so.6.1: open failed: No such file or directory

Here's my LD_LIBRARY_PATH setting:
/usr/local/sybase/lib:/usr/openwin/lib:/usr/lib:/usr/local/lib

Is there a link I'm missing or a library I need to install?

Thanks!
