compiling samba source - not working

[John Griffiths <john@capmon.com>]

Hello again

I'm trying to get samba 2.2.0a1 on a new potato box.

i've added the line

deb-src http://http.us.debian.org/debian unstable main contrib non-free

to my sources list, run apt-get update

then

apt-get -b source samba

the packages download and then i get:

dpkg-buildpackage: source package is samba
dpkg-buildpackage: source version is 2.2.0.final.a-1
dpkg-buildpackage: source maintainer is Eloy A. Paris <peloy@debian.org>
 debian/rules clean DEB_BUILD_ARCH=i386 DEB_BUILD_GNU_CPU=i386 DEB_BUILD_GNU_SYSTEM=linux DEB_BUILD_GNU_TYPE=i386-linux DEB_HOST_ARCH=i386 DEB_HOST_GNU_CPU=i386 DEB_HOST_GNU_SYSTEM=linux DEB_HOST_GNU_TYPE=i386-linux
dh_testdir
make: dh_testdir: Command not found
make: *** [clean] Error 127
Build command 'cd samba-2.2.0.final.a && dpkg-buildpackage -b -uc' failed.
E: Child process failed

can anyone advise what i'm missing?

i chose the C and C++ packages in tasksel when i was installing.

TIA

John
