[Zope] cryptmodule.c and etcUserFolder

In the docs for the etcUserFolder package, it says "you will need to either get the cryptmodule.c (from Python) and compile it, or copy your existing cryptmodule.so file into Zope's path." I don't (1) know how to compile this module, or (2) already have a cryptmodule.so. Could someone point me to docs on how to compile this module? Any and all help would be appreciated. Regards, Erick
