[Discuss-gnuradio] build error: test_gruel.o: undefined reference to symbol 'boost::system::get_system_category()'

[address@hidden]

Hi all, does anyone else get this error message when compiling
GnuRadio? This is with latest code from today's master git tree, on
Ubuntu 11.04, boost 1.42

I can bypass this by manually adding -lboost_system -lboost_filesystem
