> Alien::Gnuplot: the executable '/usr/bin/gnuplot' appears not to be gnuplot,
or perhaps there was a problem running it.  You can remove it or set
your GNUPLOT_BINARY variable to an actual gnuplot.

Your information doesn't help here.

Please provide the output of `gnuplot -V` on a system that fails, to confirm that your GNU Plot both exists, and isn't broken.

Also confirm what the output of GNUplot is when run in a terminal, after executing the command:

> show version

it should have the string

  	G N U P L O T

In it.

Thank you for the patch.

Fixed without revbump, because it is a build-time issue.
