you don't have to copy libgnokii.so.2.0.5 to /var/lib/install/usr/lib AND /usr/lib
/usr/lib is already in the search path for libraries so it might be easier
or you can user /var/lib... and modify your libray search path (LD_LIBRARY_PATH)

If you can use it from xterm and not from the menu it means that there's a problem with the com.nokia.phoneLink.service file ... I'll check it out & let you know
