jrun installation error in IA64

Hi All,
       I am trying to install jrun-4 on HP Rx2600
machine(Intel Itanium 2 processor 900MHz), which 
is running on RedHat Advanced Server 2.1(for Itanium
2)
kernel version 2.4.18-2.12smp, 
  I am getting error, when the installation starts
Error
-----
$ ./jrun-40-linux-en.bin 
Preparing to install...
Extracting the installation resources from the
installer archive...
Configuring the installer for this system's
environment...
dirname: error while loading shared libraries:
libc.so.6.1: cannot open shared object file: No such
file or directory
--------------------

what could be the problem, any body installed
successfully?

Thanks,
Bala.
