Is /usr/local/lib in the LD_LIBRARY_PATH for root user? (since you
execute with sudo which isn't necessary)
Also be sure to set up udev according to
http://gnuradio.org/redmine/wiki/gnuradio/UbuntuInstall otherwise usrp
will not be recognised.

Yes, everything would then be installed under the specified prefix
rather than /usr/local, but you would still have to add PREFIX/lib to
your LD_LIBRARY_PATH
