The actual error is about another symbol:

  _PyTango.so: undefined symbol: _ZN5Tango17ranges_type2constIjE3strE

This symbol is old ABI, as opposed to _ZN5Tango17ranges_type2constIjE3strB5cxx11E
(which *does* exist in libtango.so.8).

Can it be a bug in GCC? I don't think it should produce such a broken _PyTango.so.
