[GRASS-user] i.spectral and gnuplot

[francesco]

Can you access gnuplot from the unix bash by typing "gnuplot"?  Probably 
not since it gives that line 229 error. I don't know about Mac, but either 
you have gnuplot installed as mac binary and not accessible by the unix 
shell, or you have a different name.  Try installing gnuplot unix binaries.
