Bug#697264: cdebconf-entropy: Missing build dependency on autoconf?

[Petter Reinholdtsen <pere@hungry.com>]

Package: cdebconf-entropy
Version: 0.24
Tags: patch

<URL: http://jenkins.debian.net/job/d-i_build_cdebconf-entropy/ > report
the following build error:

dpkg-buildpackage: host architecture amd64
 fakeroot debian/rules clean
dh clean
   dh_testdir
   debian/rules override_dh_auto_clean
make[1]: Entering directory `/var/lib/jenkins/jobs/d-i_build_cdebconf-entropy/workspace'
[ -e configure ] || ./autogen.sh
./autogen.sh: 3: ./autogen.sh: autoreconf: not found

make: *** [clean] Error 2
dpkg-buildpackage: error: fakeroot debian/rules clean gave error exit status 2

Is the package missing a build dependency?  I suspect it should
build-depend on autoconf.  Here is a patch:
