Alright already.  Here is the patched file you want

http://nucular.sourceforge.net/kisstree_pickle.py

This will make all your nucular indices portable across python
versions and machine architectures.  I'll add this to the
next release with a bunch of other stuff too.

By the way there is another module that uses marshal for
strictly temporary storage in http://nucular.sourceforge.net
-- but if I change that one the build time for nucular indices
fully DOUBLES!!  That's too much pain for me.  Sorry.

Also, it's always been a mystery to me why Python can't
keep the marshal module backwards compatible and portable.
You folks seem like pretty smart programmers to me.  If
you need help, let me know.  It's a damn shame Python doesn't
have a serialization module with the safety, speed, and
simplicity of marshal and also the portability of pickle.
I guess I have to live with it :(.
