 BTW, I'm still not sure what exactly should I do to build lmi in its own
chroot so that it doesn't interfere with anything in my main system (and
notably doesn't require me to install anything into /opt or anywhere
outside of my home directory), which is why I hadn't done this myself. I'm
waiting for the stabilization of the lmi build scripts before trying to do
it, could you please let me know when should I try to test them?

 I'm going to look at those (and those for wxPdfDoc too), but probably not
right now as I still have other things to finish it looks like these
warnings will take quite some time to deal with.
