Surely you don't just get the problem by compiling and linking? What
Python do you have to execute?  My tests fail to reproduce your
problem. I can import the module and call the wrapped function. The
enclosed files can be unpacked to libs/python/test to demonstrate,
using bjam. I'm quite sure that your problem has to do with the build
system you're using, and nothing else... you can use "bjam -n -a test"
to view all of the build/test commands, so just make sure your build
system is doing the equivalent.
