Exactly:

=====
AC_SEARCH_LIBS(dirname, [gen], [have_dirname=yes], [have_dirname=no])
=====

Unfortunately, this does not search the library System.  I think "-framework
System" is what's needed, right?  If so, a block like the following can be
added above the "Checks for libraries." part of configure.in:

=====
case $host in
*-*-darwin*) LDFLAGS="$LDFLAGS -framework System";;
esac
=====

Alternately, changing the AC_SEARCH_LIBS line above to read

=====
AC_SEARCH_LIBS(dirname, [gen System], [have_dirname=yes], [have_dirname=no])
=====

might do it too.  (Of course, re-running autoconf after these changes is
required.)
