Well, I don't plan to use an application installer. Most of our users build and 
run the application from within a svn working copy.

I don't understand the intricacies of Boost's initialisation, nor do I even 
know when it happens. I naively thought that nothing would happen until I 
explicitly call a boost_python API method. Does the fact that I have included 
<boost/python.hpp> mean that some boost initialisation will occur before main() 
is reached?

Sadly, I think that is the only solution. Thanks again for your help.

Best regards
