You do not need to have boost available as a shared library.
Sorry Jan, I don't understand - how can I link my library in with the user's
local installation of Boost if it's not available as a shared library?
I do not truly have an answer for that. But if I remember correctly,
I had seen ".pic.a" libraries previously which, I would say,
would alleviate the problem, short of them being much less widespread
in use than .a archives already are.
It really seems uncommon to me for users not to have shared libraries
these days..
