Hi Marcus, Thanks for the response and thoughts.
I am running Ubuntu 12.04 on the beaglebone. I don't use any GUI, and I start the gr-ais script from the commandline. With the cortex A8 and neon co-processor the beaglebone is suprisingly powerfull. Currently I am developing on a Ubuntu 13.10 desktop with the same gnuradio (3.7.2) and with the libgruel-dev<http://packages.ubuntu.com/nl/lucid/libgruel-dev> and libgruel0 <http://packages.ubuntu.com/nl/lucid/libgruel0> package uninstalled. I don't have these available on the beaglebone. I believe when I run 3.7 with the gruelpackage remove (since it is depricated), it uses the methods from these packages. Please correct me if I am wrong on this. Maybe I will go back to 3.6 to check if the Beaglebone is powerfull enough.
