  $ c++filt _ZN7db_base4dbidEv
  db_base::dbid()


Given the missing symbol, it appears that at least part of your
installation is from a relatively recent copy of the trunk, since
db_base is part of the C++ daughterboard code.

I suggest that you remove all traces of GNU Radio from /usr/local,
then remake and install a known version (from svn or a tarball).
