I am puzzled as well. It seems the symbol ALL_GAINS is not being
exported for you. Here is the line, nothing weird about that:
http://code.ettus.com/redmine/ettus/projects/uhd/repository/revisions/master/entry/host/include/uhd/usrp/multi_usrp.hpp#L94

You said that the problem also happens with libuhd.so. So if you run the
example rx_timed_samples, the application also prints out this undefined
symbol error? If possible I would like to narrow this down to a uhd
problem or a uhd+gnuradio problem, etc...

Also, what compiler are you using? what version, etc..?
