bzr build fails for lack of python 2.5 zlib

[jim@…]

On Leopard, using Python 2.6.1 and without zlib installed, the bzr build fails like so:

--->  Building bzr

There's a stub port for py25-zlib whose description says "This is a stub. zlib is now built with python25". Installing that doesn't seem to help:

Here's some info on what I've got installed:

FWIW, zlib is present for python2.4 and python2.6

You need to update your python25, python25 @2.5.4_6 is the latest and has the zlib module:

$ port installed python25
The following ports are currently installed:
  python25 @2.5.4_6+darwin_9+macosx (active)
$ python -c "import zlib"
$
