[GRASS-user] i.spectral and gnuplot

[francesco]

Stuart,

I don't know about Mac's binaries, but i.spectral is actually a script and 
it is accessible using any editor.  Check your script folder in your grass 
distribution and remove the gnuplot check strings which Glynn pointed out.

Cheers,
Francesco
