I'm currently in the middle of making sure directfb included in
buildroot compiles properly. There are problems (I submitted the
original patch for directfb months ago) and just two days ago noticed
some dependent packages not building correctly linking against the host
libraries instead of the target ones. I'll submit a patch when I get it
all working. For instance freetype is one of the packages that is not
linking against the jpeg library in buildroot...
