   Note that you can avoid this question by passing
   the '-n' option to 'Makefile.PL'.

Install gloss.pl, a commandline graph layouter ? [y] y
You don't seem to have the optional 'Graph::Directed' package. Not fatal.
You don't seem to have the optional 'Graph::Undirected' package. Not fatal.
You don't seem to have the optional 'gnuplot' program. Not fatal
Checking if your kit is complete...
Looks good
