we have a tuxedo(BEA) python extension, the extension 
works very well under solaris/AIX, it has issue with 
HPUX(PA-RISC or ITANINM)
with python 2.3.2 and 2.3.5

_tuxedowsnmodule.so is our python interface lib, 
from 'ldd -r' output, the lib itself should not have 
any issue,
but when we tried to load it to python, it complained,

        symbol not found: main

we looked at the python source code, and think we 
found the cause of the issue:

  case $ac_sys_system/$ac_sys_release in
  AIX*) DYNLOADFILE="dynload_aix.o";;
  BeOS*) DYNLOADFILE="dynload_beos.o";;
  hp*|HP*) DYNLOADFILE="dynload_hpux.o";;
  Darwin/*) DYNLOADFILE="dynload_next.o";;
  atheos*) DYNLOADFILE="dynload_atheos.o";;
  *)

  # use dynload_shlib.c and dlopen() if we have it; 
otherwise stub
  # out any dynamic loading
  if test "$ac_cv_func_dlopen" = yes
  then DYNLOADFILE="dynload_shlib.o"
  else DYNLOADFILE="dynload_stub.o"
  fi

 
where on hpux the file dynload_hpux is used.  Looking 
inside Python/dynload_hpux.c;
 
  flags = BIND_FIRST | BIND_DEFERRED;
  if (Py_VerboseFlag) {
    flags = BIND_FIRST | BIND_IMMEDIATE |
      BIND_NONFATAL | BIND_VERBOSE;
    printf("shl_load %s\n",pathname);
  }
  lib = shl_load(pathname, flags, 0);
  /* XXX Chuck Blake once wrote that 0 should be 
BIND_NOSTART? */
  if (lib == NULL) {
    char buf[256];
    if (Py_VerboseFlag)
      perror(pathname);
    PyOS_snprintf(buf, sizeof(buf), "Failed to load 
%.200s",
            pathname);
    PyErr_SetString(PyExc_ImportError, buf);
    return NULL;
  }

We looked through the shl_load man page and found 
that Python should be using the option 
BIND_TOGETHER.  I tried it and it loads the tuxedo 
module.
shl_load man page;

BIND_TOGETHER         When used with BIND_FIRST, the 
library being mapped and its dependent libraries will 
be bound together.  This is the default behavior for 
all shl_load() requests not using BIND_FIRST.
So we changed the /Python-
2.Python/dynaload_hpux.c to;
        flags = BIND_FIRST | BIND_DEFERRED | 
BIND_TOGETHER;
        if (Py_VerboseFlag) {
                flags = BIND_FIRST | BIND_IMMEDIATE | 
BIND_TOGETHER |
                        BIND_NONFATAL | BIND_VERBOSE;
                printf("shl_load %s\n",pathname);
        }

Not sure if there is version of python without the 
bug, and if it is possible to patch 2.3.2 and 2.3.5

Python 2.3 is no longer supported.

There was a problem with not supporting .so extensions on
HP-UX for ia64.  That was committed to Python 2.5 in
revision 46046 from Bug/Patch #1481770. You can try to apply
that patch to Python 2.3 and see if it fixes the problem.  I
don't know if the patch was backported to 2.4.

If your fix works for you, I suggest running with it.  If
this problem still affects Python 2.4 or later, please
re-open this bug report.  

Note:  No Python developer has access to HP boxes AFAIK. 
It's very hard for us to verify these changes.  We have no
HP-UX boxes running the buildbot
