can't run spectrum demo on symbian/N8

Well, this one could be way out of scope but:

If you open spectrum demo in QtCreator and try to select as a target symbian device (I'm testing on N8), then:

• in compilation output you get

  Failed to find package 'C:/QtSDK/Demos/4.7/spectrum/3rdparty/fftreal/fftreal.sis': Package file not found
  

• in application output you get

  Could not start application: General OS-related error
  

Maybe it would require a bit of a change of code structure (compile fftreal in statically? change the way this dynamic lib is packaged into a .sis?) but it would be great if this kind of demos could be launched immediately out of the box...
