I'm running debian testing here, and I'm having no problems like the one you describe. However, this smells more like a gnuplot issue than anything else. Try this: 1) open gretl and try a time-series graph 2) you should have in your $HOME/.gretl/ subdir a file called gpttmp.<something>; that's a temporary gnuplot file we use for building the png file that is what you have displayed on screen (or SHOULD have displayed on screen) 3) copy that file somewhere else (say, $HOME/foo.gp) 4) open it with a text editor and remove (or comment) the first two lines 5) try gnuplot on that directly from the command line; that is, do "gnuplot -persist ~/foo.gp" If the plot appears, the problem is that for some reason your version of gnuplot has problems with generating png files. Like I said, I'm running testing and I've got gnuplot 4.2.4 here, but it appears unstable has 4.2.5. Granted, it's just a shot in the dark, but you never know.

If gretl and gnuplot don't play nice with each other in unstable, it's probably appropriate to file a bug report to the Debian guys. The Debian package maintainer for gretl, Dirk Eddelbuettel has done an outstanding job for years and I am certain he would take care of the issue appropriately, although in my eyes it's not a gretl bug, but rather a gnuplot bug.

I tried what Mr. Cottrell suggested, and I can produce a png file of sin(x) using gnuplot in unstable. But no matter how I try to set those environmental variables I can't get Gretl to switch fonts and work.

Okay, I was able to replicate the environmental variables and the command line output you showed me.

However, it had no effect on the error message from Gretl.

No, it didn't work regardless of how I set the variable I think. Would you like me to file a bug report against gnuplot?
