[Discuss-gnuradio] uhd blocks missing

Hello,

I am using ubuntu 13.10 and I installed gnuradio using the 'apt-get install gnuradio' command as described here

http://gnuradio.org/redmine/projects/gnuradio/wiki/InstallingGR

I did not experience any errors or issues with the above install. Now it's not clear to me how I should proceed to get the gr-uhd blocks to appear in gnuradio-companion so I can use my USRP N210. I've installed the uhd software as described here

after installing gnuradio (order of operations issue?) but I still don't have access to usrp_sink or usrp_source from gnuradio-companion. What steps should I take?

Thanks,
Rich
