FFS!!

So I tried some others...

 ldd /usr/bin/rxvt
        libX11.so.6 => /usr/X11R6/lib/libX11.so.6 (0x40023000)
        libc.so.6 => /lib/libc.so.6 (0x400dd000)

argh.

All that just for display. While...

 ldd /bin/bash
        libncurses.so.5 => /lib/libncurses.so.5 (0x40023000)
        libdl.so.2 => /lib/libdl.so.2 (0x40061000)

        /lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x40000000)
