please add this dependency
What is your rationale here? Libsvm runs fine without gnuplot, so I don't think we need dependency to it. (We could add gnuplot local USE flag to enable gnuplot support for libsvm, though)
The supplied python scripts installed to /usr/share/doc/libsvm-2.81/tools will not run without gnuplot.
2.84 now has tools USE flag that will pull in gnuplot as dependency
Thanks Christian. This is exactly what I wanted.
