It seems the proper way to "add to LD_LIBRARY_PATH" is not by using that env anymore, but by using ldconfig and /etc/ld.so.conf.d/*.conf files.
1. Add the ld.so configuration file : echo "/opt/qt-mobility-src-1.0.0-tp2/install/lib" | sudo tee /etc/ld.so.conf.d/qt-mobility.conf 2. Update the cache sudo ldconfig -v Now the libraries are in your ld library path. No messing with /etc/environment. And if you later decide to "uninstall" the libraries, just remove the conf file and run sudo ldconfig again. Cleaner solution for me. I just wonder if this is also portable to other distros beside Ubuntu? (since LD_LIBRARY_PATH supposedly works on all Linux distros) See http://linux.derkeiler.com/Mailing- Lists/Ubuntu/2008-02/msg02742.html for rationale.
