gnuplot woes, a second story

[chajadan]

When I try to run gnuplot from my Python2.2 installation, I get an error 
(listed below)

I'm on windows 98, I installed NumPy, I unzipped gp371w32.zip into my main 
python directory, and I tried changing the command to the gnuplot program 
FROM gnuplot_command = 'pgnuplot.exe' TO gnuplot_command = 
'c:\Python20\gp371w32\pgnuplot.exe'

I also changed the import of popen from win32pipe to os, but none of these 
configurations seem to work.

Can you help?

Here's the error:
