[Discuss-gnuradio] Installation issue -gnuradio-companion disable

During installation gnuradio, I encounter this issue. It seems gnuradio-companion is not enable. I found this recommendation though, it is not simple to install cheetah and lxml. Numpy is installed for sure in my VM(Ubuntu 14.04), but not sure of cheetah and lxml. Any advices welcomes Thanks, Ha
