Dave, this is an automake issue indeed.
i use automake 1.12.2 (as advised at http://www.open-mpi.org/source/building.php, and this is the version used to build the snapshots) automake 1.12.2 adds the following line in ompi/include/Makefile.in : $(srcdir)/mpi.h.in: $(am__configure_deps) ($(am__cd) $(top_srcdir) && $(AUTOHEADER)) rm -f stamp-h2 touch $@ there is no such line with automake 1.14 (it seems you are using automake 1.13.3, which does not issue such lines) bottom line, both web site and build systems should be updated in order to use a more recent automake version (but which one ?)
