Re: [boost] Boost.Python and ImportError

The first thought that springs to mind is that you may be using a version of
Boost.Python that's newer than your library. Did the library come with your
Linux distribution/in some RPM, or did you build it yourself from the same
boost sources against which you're compiling your module?
