HPUX 11i have prebuild OpenSSL package (current  A.00.09.07i.002/003).
Entropy source is documented by HP on:
http://h20293.www2.hp.com/portal/swdepot/displayProductInfo.do?productNumber=OPENSSL11I
and it depends on HPUX version You use:
-hpux11iv1(11.11) - /dev/urandom, /dev/random, /opt/openssl/prngd/prngd
        but has no /dev/random, /dev/urandom installed by default
-hpux11iv2(11.23) - /dev/urandom, /dev/random, /opt/openssl/prngd/prngd
        has /dev/random, /dev/urandom installed as kernel module by default
