Usrp_sink trouble

Hi all,

I can’t get the usrp_sink and usrp_source blocks to show up in gnu
radio. I followed the instructions here:

http://code.ettus.com/redmine/ettus/projects/uhd/wiki/UHD_Linux

I installed the Master/Unstable version. It completed without an error
but when I open gnu radio I don’t see the blocks.

Can someone help me out?

Thanks,
Rich
