        <div>If you have libjpeg installed (check the first step), then
          it's very likely your symlinks under /usr/lib are screwy for
          some reason... if that's the case fixing without breaking
          other stuff is the trick (my guess is you'll just need to do
          'sudo ln -s ./libjpeg.so.62.0.0 ./libjpeg.so.62' in that
          directory, but that's just a guess.... &nbsp;I've never fully
          understood the logic behind how library versioned /
          named-linked are supposed to work, but tinkering around will
          either lead you to success or an unusable system... :-)&nbsp;</div>
