Error using Aqua Term with gnuplot 4.1

[Jeremy C. <jer...@gm...>]

I have an Apple PowerBook running OS 10.4.  I just installed gnuplot
version 4.1 because I need to plot errorbars with histeps.  I only had
one problem with the installation but was able to get around it.  The
problem was in the LaTeX tutorial and I simply disabled it.  Now when
I run gnuplot, every time it tries to plot, Aqua Term opens but a
window never opens and a plot is never displayed.  I finally get an
error that says:

2005-11-26 09:00:16.828 gnuplot[2941] *** Uncaught exception:
<NSInvalidReceivePortException> connection went invalid while waiting
for a reply
Trace/BPT trap

Can anyone help me with this?  What do I need to do to get this to work?
Thanks,
Jeremy
