If you look in random.h there two places with:

#if defined(__svr4__) || defined(__SVR4)

add a ``|| defined(YOUR_HPUX_SYMBOL)'', replacing YOUR_HPUX_SYMBOL
with something that your compiler defines (or something you manually
define :-) and I expect you'll be OK.

The next version of ns will replace the random number implementation,
eliminiating this problem.
