Your understanding is correct. If a module requires a Python 
extension module written in C, you cannot use that module in Jython.

Your best option is to find another library that is either pure 
Python (no C extensions needed) or Java (Java libraries are usable 
from Jython). Other options are to rewrite the library so it doesn't 
need the C extension, or port the C extension to Java to create a 
Jython version (BTW this has been done with many library modules 
already).
