This has been addressed many times on the mailing list. It’s an OpenGL
issue. First, you can probably install python-opengl on your system.
Or you can turn of GL support by editing the file in (probably)
/usr/local/etc/gnuradio/conf.d/gr-wxgui.conf and change the ‘style =
auto’ option to ‘style = nongl’.

See if the easy install instruction for pyopengl helps you:
