No module named zlib

[Ben Giles]

Hello,

I installed bazaar via macports, as per http://bazaar-vcs.org/MacPorts.

I have Mac OS X 10.5 and have installed XCode.

zlib is installed, though I don't know about the python bindings:

Goose:bzrroot ben$ sudo port install zlib
Skipping org.macports.activate (zlib ) since this port is already active
--->  Cleaning zlib

I would have thought the MacPorts package would install all  
dependencies?

I get the following error when attempting a checkout- any help would  
be appreciated:

Goose:bzrroot ben$ bzr checkout http://bazaar.ubercart.org/ubercart/alpha/ubercart
bzr: ERROR: exceptions.ImportError: No module named zlib
