If you have a 32-bit compiler then your current spec should already support
32-bit applications. On my machine, the 32-bit compiler files (libs) are in
/usr/lib/gcc/x86_64-pc-linux-gnu/3.4.6/32/*.

What happens if you try:
> cp /opt/wengophone/qtwengophone /tmp
or
> cat /opt/wengophone/qtwengophone > /dev/null

Also, are you able to interpret the format at all:
What does
> ldd /opt/wengophone/qtwengophone
return?

Do you get any denial messages in dmesg (i.e run dmesg, do you see anything
out of the ordinary. If there is any doubt post your dmesg log)
