I’m running gnuplot from the tools menu of Gretl 1.10.1 (same problem in latest gretl from
CVS).
On OS X Yosemite with the Quartz version Gretl.
Gnuplot starts but when I issue the help command in gnuplot gnuplot responds with
/Applications/Gretl.app/Contents/Resources/bin/../Resources/share/gnuplot/4.6/gnuplot.gih:
No such file or directory
and no help is shown.
