[GRASS-user] i.spectral and gnuplot

[Stuart Edwards]

Francesco

Ok -- that was straight forward (in the grand scheme of things) --  
thanks.   Now when I run i.spectral the following error is returned:

line 229: gnuplot: command not found

Is this a path problem on my part or something in the script?  Is  
$GNUPLOT  (from line 229) the same as GRASS_GNUPLOT (the  
environmental variable)?  Wish I knew more about this!  Thanks for  
any advice.
