[Discuss-gnuradio] QT Time Raster in OSX 10.10.4 Not Rastering

The QT Time Raster GUI doesn’t appear to function in the latest gnuradio-devel 
macports. The plot appears all a single color although the bits into the graph 
are not constant. I run the same flow graph on my Ubuntu setup and I get the 
rastered bits plotted as expected. I’m using:

 gnuradio-devel 
@20151111_0+docs+grc+jack+portaudio+qtgui+sdl+swig+uhd+wavelet+wxgui  
OSX 10.10.4

Simple example: Raster some bits with the gr_time_raster_b
 gr_time_raster_b bits.b8 

Output:
Using Volk machine: avx_64_mmx_orc
Warning: QWT5 has been found which has serious performance issues with raster 
plots.
         Consider updating to QWT version 6 to use the time raster GUIs.

The problem with this warning is that it appears it is nontrivial to use QWT6 
with OSX on the current gnuradio builds.  

Does anyone else have this problem? Does it work in the gnuradio (non-devel) 
port?
