Building Octave with SuiteSparse-4.0.2 I still encounter the errors below 
(during the link phase for liboctave)

Undefined symbols for architecture x86_64:
  "_SuiteSparse_time", referenced from:
      _umfpack_tic in libumfpack.a(umfpack_gn_tictoc.o)
      _umfpack_toc in libumfpack.a(umfpack_gn_tictoc.o)

A google (link below) indicates this problem can be fixed.

        http://trac.macports.org/ticket/35176

When linking to libumfpack.a we must also link to libSuiteSparse.dylib.  I 
manually edited the Makefile for liboctave and added -lSuiteSparse to the 
UMFPACK_LIBS variable.

        UMFPACK_LIBS = -lumfpack -lSuiteSparse

liboctave now builds for me.  I'll continue with my Octave build and report 
back later.
