I know this is an mpi question but I'm wondering if I could get some
help here.  

I'm trying to compile octave-mpi, the source of which I obtained from
hpc.sourceforge.net.  It is an OSX site, but the source is just source
from what I can tell.  It is source with an mpi patch version run
against octave-2.1.31.   I keep getting hung with something to do
with the stl libraries of gcc.  Here is my gcc, make, and system info
followed by my error output:

---------------

This is what I see in the function in CColVector.cc:
60:bool
61:ComplexColumnVector::operator == (const ComplexColumnVector& a) const
62:{
63:  int len = length ();
64:  if (len != a.length ())
65:   return 0;
66:  return equal (data (), a.data (), len);
67:}

This is what I see stl_algobase.h
664:   *  This compares the elements of two ranges using  at c == and
returns true or
665:   *  false depending on whether all of the corresponding elements
of the
666:   *  ranges are equal.
667:  */
668:  template<typename _InputIter1, typename _InputIter2>
669:    inline bool
670:    equal(_InputIter1 __first1, _InputIter1 __last1,
671:          _InputIter2 __first2)
672:    {
673:      // concept requirements
674:     
__glibcpp_function_requires(_InputIteratorConcept<_InputIter1>)
675:     
__glibcpp_function_requires(_InputIteratorConcept<_InputIter2>)
676:      __glibcpp_function_requires(_EqualOpConcept<
677:            typename iterator_traits<_InputIter1>::value_type,
678:            typename iterator_traits<_InputIter2>::value_type>)
679:                                                                                                    
680:      for ( ; __first1 != __last1; ++__first1, ++__first2)
681:        if (!(*__first1 == *__first2))
682:          return false;
683:      return true;
684:    }


I'm clueless as to how to fix that or what is wrong.  Any suggestions?  

Thanks in advance!
