Como instalar corretamente o GNU Radio

Question

Estou executando Debian 4.9.110-3 e instalei GNU Radio com Synaptic . Eu também instalei gr-osmosdr . Eu tentei reunir um osmocom-Source e um QT GUI Frequency Sink . Quando corro eu tenho

Eu baixei uma imagem recente de Pentoo , onde tudo funcionava desde o início (no Virtualbox). Eu também instalei um recente Kali linux no Virtualbox, e como ele não tem GNU Radio pré-instalado, instalei seguindo os passos usados para o meu sistema Debian host, mas recebi o mesmo erro. Eu também tentei instalar qjackctl , mas começar a congelar meu desktop. E o Pentoo não tem qjackctl . Talvez existam algumas dependências ou configuração que eu esteja faltando?

Estou apenas experimentando com GNU Radio , não tenho nenhum SDR anexado.
