I have a USRP1 with a WBX and a DBSRX installed. Everything worked fine with the gr-3.3.0-rc3 and even several months ago when I started using Marcus Leech's script. But lately (within the past few weeks) when building the latest GR+UHD (with ML's script), if I run a flowgrpah that uses the DBSRX or uhd_usrp_probe, I get an error message like the one below. Does anyone know why this might be occurring? Apologies if this is better suited for the USRP USers group.

address@hidden:~$ uhd_usrp_probe
linux; GNU C++ version 4.5.2; Boost_104200; UHD_003.004.000-dac9a50
