error compiling under 11.23

Hi,

I'm trying to compile postgressql 7.3.2 on HP-UX B.11.23 ia64.  But I get
the following error:

I see a newgroup posting about this same error from november 2002.

But I don't see any solutions.  Has anyone gotten postgres to
compile on ia64-hpux?  I actually just need libpq.sl for the
ruby-postgres module.  This module provides client connectivity to
postgres through ruby.  Thanks for any help.
