1/ You might look at MeeGo CE rather than nemo, as Nemo can use mlite (a subset of meegotouch) 2/ And what about putting the library into /opt/xcb/ or so? 3/ What about, as a next goal, upgrading x11 as a whole? Some packages are already in -devel. (x11proto-input-meego-dev & etc. - the names are changed).
