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

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
