This is a fix which "just happens to work" but it won't do so 
reliably. I would strongly recommend finding exactly which part of 
either Boost or your code is missing its proper visibility 
declarations and fix it.

I'll be running a test build of TnFOX this summer (hopefully as part 
of GSoC), so if Boost.Python has introduced a regression I'll find it 
and fix it then.

Cheers,
