        Hi,
         
                I am getting the following error when running build using 
automake:


                cd /tmp/build123/src/bison-1.28 && automake --gnu 
--include-deps Makefile
                automake: configure.in: required file `./config.guess' not found
                automake: configure.in: required file `./config.sub' not found
                make[1]: *** [/tmp/build123/src/bison-1.28/Makefile.in] Error 1
                make[1]: Leaving directory `/tmp/build123/build/bison'
                make: *** [/tmp/build123/build/bison/flag-built] Error 2
                
                Please send some suggestions on how to resolve this problem.
