Comment (by michaelld@…):

 This is a somewhat complicated issue; let me try to explain.

 PyQwt is quite old; it works with Qt4 and QWT5 only for all practical
 purposes. There is a note I left in the Portfile that it is not compatible
 with QWT6, in this case the 6.0 series. I doubt it is compatible with
 QWT6+ at all. QWT continues development while PyQwt has not changed in
 years & I have seen no sign that it'll be taken over and updated.

 We will be moving Qt4 (qt4-mac) install locations, which will require
 updating a variety of ports -- hopefully most will be a simple rev-bump. I
 think many Python ports will be a pain to get to work; they generally are
 tweaky when it comes to specifying arguments & such, preferring to do that
 on their own. PyQwt is likely to be one of these ports that will require
 attention to get working.

 There are good uses for QWT5 and QWT 6.0+. Right now, these are installed
 as libraries (e.g., $PREFIX/lib/libqwt.5.2.3.dylib). Moving the install to
 Frameworks should be pretty straight forward, and would allow for multiple
 versions to be active at the same time. In this manner, GNU Radio can use
 PyQwt for its one remaining application (the filter design tool), but
 other ports could use QWT6+ directly. It'll take some work to get to this
 point, and I'm not sure when I'll have time -- maybe I'll try to do this
 during the Qt4 switch-over.

 Anyway, it's an interesting and complicated problem. Please be patient; I
 do want this fixed, but also fixed correctly.
