if it works with perl but not with mod_perl then IMO the apache binary is not
proper build for H-UX Oracle. Please check via

  chattr <apache-sbin>/httpd

that you find in the "shared library list:" section

   /usr/lib/libpthread.1
and
   /usr/lib/libcl.1

if shared library list of

  chattr /post/opt/perl-5.8.0/lib/site_perl/5.8.0/PA-RISC2.0/auto/DBD/Oracle/Oracle.sl

also contains /usr/lib/libcl.1. Both library must be linked to the main-programm if a
shared lib or object needs it. Strange or simpler HP-UX ;-).
