After a bit of digging around and trying different things, I think I have a grasp of what is going on.
For whatever reason, I had qwt @5.1.2_2+qt4 (active) and py27-pyqwt @5.2.0_4 (active) installed. It seems that the current version of gnuradio (3.7) uses qwt52. I uninstalled all qwt related packages (port installed | grep -i qwt) and installed qwt52 and gnuradio sudo port install qwt52 sudo port install gnuradio +full It then completed without errors. Michael, thank you for your help. _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org https://lists.gnu.org/mailman/listinfo/discuss-gnuradio
