Why don't you extract the data files inside the deb files, get the required libraries, put them in a folder, compile the missing ones (that will bring up MORE dependencies, which will need more compiling and more dependencies) and then append that folder to the library path with the terminal, extract the wazapp deb data file to N900 root and launch wazapp?? Maybe this could work, insane amount of compiling probably ahead or some N9 specific Harmattan calls make ti segfault and all hours of work are for nothing, not willing to risk throwing so many hours away
