Unmet build dependencies for openssh?

[harlan@artselect.com (Pete Harlan)]

I'm trying to recompile ssh in the Sarge pure64 archive from
http://amd64.debian.net/debian.  I've retrieved the source with
"apt-get source ssh", but don't seem to be able to build the package:

	% apt-get build-dep ssh
	Reading Package Lists... Done
	Building Dependency Tree... Done
	E: Build-dependencies for ssh could not be satisfied.
	%

When I try to build anyway, it says:

	% dpkg-buildpackage -rfakeroot -b
	dpkg-buildpackage: source package is openssh
	dpkg-buildpackage: source version is 1:3.8.1p1-8.sarge.4
	dpkg-buildpackage: source maintainer is Colin Watson <cjwatson@debian.org>
	dpkg-buildpackage: host architecture is amd64
	dpkg-checkbuilddeps: Unmet build dependencies: libwrap0-dev | libwrap-dev zlib1g-dev | libz-dev libssl-dev libpam0g-dev | libpam-dev libgnomeui-dev (>= 2.0.0) | libgnome-dev debhelper (>= 1.1.17)
	dpkg-buildpackage: Build dependencies/conflicts unsatisfied; aborting.
	dpkg-buildpackage: (Use -d flag to override.)

When I override with "-d", it says:

	% dpkg-buildpackage -rfakeroot -b -d
	dpkg-buildpackage: source package is openssh
	dpkg-buildpackage: source version is 1:3.8.1p1-8.sarge.4
	dpkg-buildpackage: source maintainer is Colin Watson <cjwatson@debian.org>
	dpkg-buildpackage: host architecture is amd64
	 fakeroot debian/rules clean
	dh_testdir
	make: dh_testdir: Command not found
	make: *** [clean] Error 127

...and I'm lost.  Is it possible to rebuild this package within the
pure64 archive?

Many thanks,
