Python 2.1.1 does build for HPUX 11.00 when using gcc 3.0.2.
There is the final link that needs to be done by hand though, if python is 
built with --enable-threads  (which is required for omniORBpy, but probably 
not just for omniidl).

I think there are major problems with C++ parts of gcc 2.95.2 on HP-UX - 
mainly related to exception handling.    gcc 2.95.2 is not even officially 
supporting HP-UX.

gcc 3.0 2 does support HP-UX 11.00 a bit better, but still has problems with 
omniORB,  crashing during compilation of poa.cc.

I've filed a gcc bug report 4351 which you can view at  in internal 
http://gcc.gnu.org/cgi-bin/gnatsweb.pl

>From the above mention report, gcc 3.0.2 dies when compiling the following 
code fragment on HP-UX 11.00.

-------------------------------------------------------------
 class Exception {
 public:
   virtual void _raise() = 0;
   inline Exception() {}
   inline Exception(const Exception& ex) {}
 };
  
 class AdapterAlreadyExists : public Exception
 {
   virtual void _raise();
 };
  
 void AdapterAlreadyExists::_raise() { throw *this; }
----------------------------------------------------------------


I've ported omniORB to KAI C++ on HP, but I would rather be using gcc.  So 
far I haven't had any luck,  even after investing considerable amount of time 
to it.
