Debian binaries failed compile

Debian Woody Box

I need Samba compiled --with-winbind-auth-challenge option (for 
squid/NTLM authentication).

I downloaded the source package from samba ftp server (2.2.8a), 
installed it with apt-get source samba, changed to /debian and edited 
rules script:

--with-winbindd \
--with-winbindd-auth-challenge \      <- the only row I added
--with-msdfs)

When I try compile the binary with debian/rules binary it fails:
dh_testdir
make: dh_testdir: Command not found
make: *** [patch-stamp] Error 127

Whats happening? How can I compile samba?
