The set_clock_source() call requires the master branch of UHD. This will
be tagged as release very shortly. The previous call was
set_clock_config(), this should still work, but GRC will not generate
calls to set_clock_config() on the version of gnuradio you have.
Can I recommend you marcus's build script as an easy way to install uhd
and gnuradio master branches?
