 Building port octave on 10.7.4 gives the following error:
 {{{
 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)
 ld: symbol(s) not found for architecture x86_64
 }}}

 The issue is due to ''UMFPACK_LIBS'' provinding only '''-lumfpack''' flag
 and the missing symbol being defined in libSuiteSparse.dylib rather than
 libumfpack.a (both are from port SuiteSparse).

 I'm patching UMFPACK_LIBS in Makeconf file in post-configure phase.
 This ticket acts as memo, I'm cc'ing original reporter on mp-user list
