[Gnuplot-info] path problem with gnuplot and x11 on mac os 10.3.9

[Wayne S. <ws...@ta...>]

First, I think that what you folks are doing is fabulous.  But I've got 
problems.

I just installed gnuplot.  x11 was already installed, as was acquaterm.

Problem 1 may be stupid:

If I try to get gnuplot from Terminal, I get the gnuplot login info, 
followed by
***
Terminal type set to 'unknown'
***

If I try "set term x11" I get the response
***
Terminal type set to 'x11'
Options are '0'
gnuplot>
gnuplot: unable to open display ''
gnuplot: X11 aborted.
***

Problem 2 is curious:
If I open a window in xterm, gnuplot is defined only in the home 
directory.  I thought that I had added the appropriate path to 
etc/usr/csh.login.  Perhaps you can tell me the path to use?  I've 
tried looking up solutions on the web, but so far no go.

Many thanks.
