Help, Compile / debug Python 2.2.1 64 bit on AIX

[Davide Tacchella]

I'm trying to build Python with 64 bit support on AIX, so far I've encountered 2 problems,
dynload_aix.c is not 100% 64 bit compliant (it includes some cast from pointer to (int));
this was causing python to SEGV when building extensions, after changing from int to long, 
the error is now ILL (SIGILL), there is a pointer to NULL:
The call stack from debugger is:
0x000000
initstruct (structmodule.c - line 1508)
_PyImport_LoadDynamicModule ( importdl.c - line 53)
load_module (import.c - line 1365)
import_submodule (import.c - line 1895)
load_next (import.c - line 1751)
import_module_ex (import.c - line 1602)
PyImport_ImportModuleEx (import.c - line 1643)
builtin___import__ (bltinmodule.c - line 40)
PyCFunction_Call (methodobject.c - line 80)
eval_frame (ceval.c - line 2004)
....

Any idea ?
Any help is always welcome.
