I don't have a linux box to check this on, but how about something like...
if [ `ldd $PHARO_VM 2>/dev/null | grep -c 'not found'` -ne 0 ]; then
echo "Missing library dependencies..."
ldd $PHARO_VM 2>/dev/null | grep 'not found'
echo "Maybe you need to..."
echo " $ sudo dpkg --add-architecture i386"
echo " $ sudo apt-get update"
echo "and for each $MISSING_LIBRARY..."
echo " $ sudo apt-get install $MISSING_LIBRARY:386"
exit 1
fi
