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,

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
