Let's start with some good advice: 0.9.2b is dead and gone, we are at 0.9.6
now with a lot of enhancements and bugs fixed. It is worth to upgrade!
Now to your problem: __umoddi3 is a symbol created by gcc that is satisfied
by linking against -lgcc. This should happen automatically when also linking
with gcc. I have seen these problems when linking in a gcc-compiled library
when actually using the normal cc on HP-UX (this should also apply to all
other platforms not using gcc as normal compiler). There are two possible
solutions: recompile openssl with the native compiler of your platform
or explicitly link agains libgcc by adding
-L/usr/local/lib/gcc-lib/hppa2.0-hp-hpux10.20/2.95.2 -lgcc
(your location of libgcc.a may vary).
Best regards,
Lutz
PS. This problem is not related to your des.h header problem.
