Maybe Term-Gnuplot should be added to the tree.

Created attachment 212821 [details] Term-Gnuplot-0.90380905.ebuild Installs here fine but fails FEATURES="test" Can't load 'blib/arch/auto/Term/Gnuplot/Gnuplot.so' for module Term::Gnuplot: blib/arch/auto/Term/Gnuplot/Gnuplot.so: undefined symbol: title at /usr/lib64/perl5/5.10.1/x86_64-linux/DynaLoader.pm line 200.
If nobody really wants Term::Gnuplot then we shouldn't add it. I don't think we can or want to support every optional dependency. Term-Gnuplot seems to test for a number of libs. So it's real work to add an ebuild for it. For me: IDONTWANTIT.
WONTFIX until really needed or wanted.
