Comment:

 Sage may not need it, but the rest of the prereq build system does:

 {{{
 prereq-0.9 $ make
 (CDPATH="${ZSH_VERSION+.}:" && cd . && /bin/sh
 /home/mjo/src/sage-4.8.alpha3/spkg/build/prereq-0.9/missing --run
 autoheader)
 autom4te-2.68: need GNU m4 1.4 or later: /usr/bin/m4
 autoheader-2.68: '/usr/bin/autom4te-2.68' failed with exit status: 1
 make: *** [config.h.in] Error 1
 }}}

 We could probably ship a pre-built `configure` and `Makefile` rather than
 rely on autotools, but this is black magic to me and I don't understand
 the tradeoffs involved.
