The version of Volk currently installed is too new for the version of GNU Radio you're trying to build. I'm not 100% clear on how to install different recipes in PyBOMBS, but if you can do so try a newer version of GNU Radio (if you search the GIT logs for "volk_32f_8u_polarbutterfly_32f" you'll find the commit to be at least a recent as). Hope this is useful! - MLD
