you seem to have a version older than 11 May. here is the history:

try

GRASS_GNUPLOT="/sw/bin/gnuplot -persist"
export GRASS_GNUPLOT
i.spectral

if /sw/bin/ is in your $PATH, then you don't need any of this.
does "which gnuplot" work from the terminal prompt?

perhaps add to ~/.grass.bashrc:

GRASS_ADDON_PATH=/sw/bin
export GRASS_ADDON_PATH
