>Description:
By default, Gnuplot doesn't require teTeX-base (kpsexpand) at all and the dependency should be controllable via WITH_XXX or WITHOUT_XXX knob.

Note that Gnuplot *may* require kpsexpand if --with-kpsexpand argument is given to configure, math/gnuplot always gives it, though it is disabled by Gnuplot default.
>How-To-Repeat:
By installing math/gnuplot via ports also installs teTeX-base and its dependency.
>Fix:
Apply the attached patch to add knob WITHOUT_KPSEXPAND which makes math/gnuplot not to depend on print/teTeX-base if defined.

Patch attached with submission follows:
