Maxima uses gnuplot to do its plotting, so gnuplot must be installed. 
This last line tells you that 'gnuplot' has not been found. It is likely
not installed on your machine (?). Try

apt-get -s install gnuplot

to simulate (-s) the installation of gnuplot. To actually install
gnuplot, remove the '-s' from the line above.
