yes there is:
I've put the boost work I did with the help of other people here:
http://gnutoo.homelinux.org/open_embedded/boost.tar.bz2
I didn't have the time to finish my work because I had a segmentation
fault in boost with wesnoth-1.6x so I didn't commit it yet because of
the lack of skills and time to debug it(I don't know C++,I just learned
it a bit for this precise problem)
