Install tcsh on HP-UX 11.31 itanium

I have 2 servers , both are HP-UX
specifications as follows :

(1) HP-UX adroit B.10.20 A 9000/785 2013264127 one-user license

(2) HP-UX xen B.11.31 U ia64 2662515494 one-user license

First one has tcsh installed

adroit:/home/seo/hitendra 22 ] which tcsh
/usr/bin/tcsh

But the second one has not

 
xen:/home/seo/hitendra 29 ] tcsh
tcsh: Command not found.

I want to install tcsh on the 2nd HP-UX server.
