Samuel,
Out of curiosity, did you get this issue resolved? If so, do you mind
sharing what you did. I'm working through the same problem that you
had right now. Building against the python distributed libffi fails,
as does building against libffi2 and libffi3 available from the sarge
apt repository. I will continue working toward a solution, but if you
know the fix, that could save me a lot of time.
Thanks in advance for any help you can offer.
Tom.
