Comment (by neteler):

 Replying to [ticket:3552 marisn]:
 > From the code of i.spectral I could not figure out what should happen
 when gnuplot is absent – should it plot on screen? Into a file?
 > In either case, code needs enhancements to handle corner cases (i.e.
 output file not provided or is not writeable).

 I suppose that the default should be output into a PNG file.
