You are running the Second Life Viewer on a x86_64 platform.  The
most common problems when launching the Viewer (particularly
'bin/do-not-directly-run-secondlife-bin: not found' and 'error while
loading shared libraries') may be solved by installing your Linux
distribution's 32-bit compatibility packages.
For example, on Ubuntu and other Debian-based Linuxes you might run:
$ sudo apt-get install ia32-libs ia32-libs-gtk ia32-libs-kde ia32-libs-sdl
