[scribus] Trying hard to build 1.3.5

[John Culleton]

I just installed Debian testing for the specific purpose of building 
the bleeding edge version of Scribus. Scribus 1.3.5 requires cmake. I 
downloaded build-essential, qt4 and cmake. Ran svn of course.  When I 
try to run cmake I get this error:
 Qt4 Found OK
CMake Error 
at /usr/share/cmake-2.6/Modules/FindPackageHandleStandardArgs.cmake:52 
(MESSAGE):
  Could NOT find ZLIB
Call Stack (most recent call first):
  cmake/modules/FindZLIB.cmake:47 (FIND_PACKAGE_HANDLE_STANDARD_ARGS)
  CMakeLists.txt:428 (FIND_PACKAGE)

I ran apt-cache search zlib 
and variations thereof but no joy so far. I need to download something 
but I don't know what.

I am a noob in Debian but have a decade or so using Slackware.
