More about this error. I fetched GCC 4.6 source files, and here is what's  
in `targparm.adb`, around line 177:

     if Text = null then
        Write_Line ("fatal error, run-time library not installed  
correctly");
        Write_Line ("cannot locate file system.ads");
        raise Unrecoverable_Error;
     end if;

And `Text` is declared as `Text : Source_Buffer_Ptr;`.

So, the runtime library is not installed correctly, but what is not  
correct, remains to be answered. If the exception is raised when a `Text`  
parameter is `null` and that `Text` parameter seems to be related to  
source file, does this means it can't find the source file? But the layout  
of the `runtime` directory looks OK, it contains the `adainclude`  
subdirectory, with a copy of all of the runtime source files.
