+   If Bob <= 1.2.1 is installed on your python path, nose will automatically
+   load the old version of the insulate plugin available in Bob, which will
+   trigger the loading of incompatible shared libraries (from Bob itself), in

+   the centrally installed version of Bob, or build your own version of Python
+   in which Bob <= 1.2.1 is not installed.
