configure binutils on hpux10 machine

[Bob Rossi]

Hi,

I'm trying to build binutils-2.15 on hp 
   $ uname -a
   HP-UX hp3 B.10.20 A 9000/785 2015288828 two-user license

because I need to build gcc4. 

However, when I configure binutils on this machine, I get the message,
   checking for a BSD compatible install... ../binutils-2.15/install-sh -c
   *** This configuration is not supported in the following subdirectories:
        ld
       (Any other directories should still work fine.)

My questions are, 
   Is it normal that ld can not be built on this system?
   Does anyone know if I need ld to build to get gcc4 to compile?

Thanks,
Bob Rossi
