 octave @6.1.0 has a new font defaulting mechanism that is qt 5.2+ only,
 committed here:

 <https://github.com/gnu-
 octave/octave/commit/fbaee01b2c64ee952412e11b53b047f1f1351724>

 To make octave build and run using qt4, I came up with a fallback
 implementation for qt4 based on the previous, here:

 <https://github.com/macports/macports-
 ports/blob/3b14745f335dcc98074eb79cd98f278f36a2eb39/math/octave/files
 /patch-octave6-qt4-fixes.diff#L39>.

 but it is not working quite right. When octave 6.1 is installed with the
 qt4 variant, the system font is not picked up correctly. Usually, for me,
 the octave system default is coming in as Spanish, but just for fun, some
 of the buttons seem to be in Katagana. :>

 Opening the Octave preferences pane in qt4 (once you figure out which one
 it is, in the foreign language) gets you to a dialog where you can
 specifically set the language you want, instead of the system default, and
 then it works fine.

 Obviously my fallback is not working as hoped. There is some information
 [https://stackoverflow.com/questions/1468022/how-to-specify-monospace-
 fonts-for-cross-platform-qt-applications here]  on how this is supposed to
 be set up, and qt's info is
 [https://doc.qt.io/qt-5/qfont.html#defaultFamily here].
