'undefined symbol error while importing C ++ module

I have a python script that runs another python script and the last script imports a module. It cannot do this and returns the following:

Traceback (most recent call last):
  File "/some/path/script.py", line 13, in 
    import Autodock as AD
  File "/some/path/to/module/Autodock.py", line 30, in 
    import BALL
  File "/usr/lib/pymodules/python2.7/BALL.py", line 1, in 
    from BALLCore import *
ImportError: /usr/lib/pymodules/python2.7/BALLCore.so: undefined symbol: _ZN4BALL25FragmentDistanceCollectorclERNS_9CompositeE

However, it loads successfully when I just open the python interpreter and type this:

>>> from BALLCore import *

      

        
        
        
      

    

Other scripts that also run /some/path/to/module/Autodock.py

(which is the script importing the module) succeed. What allows them to successfully import a module from the same module?

I need to excuse myself for not sharing so much code because I have no idea where to look. Any guidance would be appreciated.
