It looks like your LD_LIBRARY_PATH isn't pointing to the lib directory
where libuhd is located. When you installed UHD, where did you install
it into? It's likely that you just have to 'export
LD_LIBRARY_PATH=/usr/local/lib' (change that last part to wherever
libuhd.so is). You _may_ have to run 'sudo ldconfig', too.
