cycloneIII I/O error in Quartus 9.1 while cycloneII succeed.

I use alt_inbuf with cycloneIII got this error:

--- Quote Start ---

Error: The location assignment on the I/O primitive instance "pad_in_pullup_cell_01" specifies an exact pin location. This is not supported for the Cyclone III family in the current version of the Quartus II software. File: /home/write-able/3/src/top.v Line: 20

--- Quote End ---

If I change to use a cycloneII, all OK.

Does anyone know why ?

    Are there Altera Quartus's people ?

    Do you think the quartus runs error , or the usage of the cycloneIII's I/O pins' location in my verilog HDL is error ?

    Do you have a particular reason not to use the standard method to assign pin locations? It's convenient with the Pin Planner tool.

    What's the "standard" method ?

    I am a ASIC designer. I always works under CLI , or Altera called command console mode.

    I never use GUI of Quartus before when I use cycloneII. And all works well.

    But, now, I change to use cycloneIII, I failed, for the Quartus software !

    Or , not the software ? Do you change the pin assign mode under CLI ?
