I just downloaded and installed the new gretl version (1.7.8)

The first error says something like this: "The picture file

Otherwise, the text output seems to be ok.
This is the shell output:

Thanks for the detailed report. I'll investigate. In the
meantime, I should say that the use of "dumbplot.gp" is a
work-around for features missing in gnuplot versions lower than
4.3.
As you may know, gnuplot has a rather conservative release
schedule. Version 4.3 has been in progress for a long time, but
is still in CVS. Gretl ships a gnuplot 4.3 CVS build in both the
MS Windows and OS X packages, and I'm pretty sure that if you
download and install the current gnuplot 4.3 from CVS the problem
you mention will go away. Nonetheless, the problem ought not to
arise with earlier gnuplot versions, so I'll do some
experimentation.
