Hi.  I'm a lead developer for gnuplot.

Unfortunately this issue appeared just at the time we were putting out
a release candidate for a major version upgrade to gnuplot 5.0.
I don't think it is realistic for us to promise support for 
wxwidgets3.0 any time soon since the amount of revision required is
unknown at this point.   I have added a warning in the Release Notes.

   http://gnuplot.sourceforge.net/ReleaseNotes_5_0_rc1.html

Would it be an acceptable option for Debian to provide a default
build that uses Qt5 (or Qt4 for that matter) libraries rather than
wxWidgets?  We spent a lot of effort over the last year or so 
polishing gnuplot's qt terminal and infrastructure, to the point
where it is now faster and more performant than wxt.  
If your default gnuplot package doesn't require wxWidgets at all,
then the wx version becomes moot.

For the gnuplot version 5.0 release candidate this corresponds to
build options

  ./configure --disable-wxt  --with-qt=qt5

(or --with-qt=qt4).
