It looks like you didn't setup QtCreator correctly, your poky cross-gcc 
is not on the PATH (or is after /usr/lib/gcc-cross/arm-linux-gnueabi/...)

make sure that arm-linux-gnueabi-g++ refers to /opt/poky/1.6.1/... and 
not /usr/lib/gcc-cross/..., from a console you can check for this with 
this command:
$ which arm-linux-gnueabi-g++

Or set the full path to your cross-gcc in QtCreator "Build&run" config.

Actually, I've just check the url you gave and obviously you didn't do 
(correctly) the 3 steps they give in "Configure Qt creator"
