How do I install on OSX

I've never tried this myself, so I can't help much. But here are some rough steps:

1. Install the Qt binary package from http://trolltech.com/developer/downloads/qt/mac
2. Install PyQt4 http://www.riverbankcomputing.co.uk/pyqt/download.php
      - there are no binaries for Mac, you will need to compile it
      - make sure you are configuring it with the version of Python that is used by bzr, not Apple's 2.3
3. Download the source code from https://launchpad.net/qbzr/+download and unpack it to ~/.bazaar/plugins/qbzr

Just confirming: The above suggestion from Lukáš Lalinský worked great for me...

It seems that the PyQt4 URL has changed to: http://www.riverbankcomputing.co.uk/software/pyqt/download

Other than that, the instructions worked for me too!

I'm having the following issue on Mac OSX 10.5 Intel upon calling 'bzr qlog':

bzr: ERROR: QBzr require at least PyQt 4.1 and Qt 4.2 to run. Please check your install

I installed PyQT4 and QT4.5. I also did a: 'python configure.py > python setup.py build > python setup.py install'

Anyone have this problem?

Will appreciate your help.

In order to install PyQt, you need to have SIP installed.
1) download and install QT4.x

2) get SIP from http://www.riverbankcomputing.co.uk/sip/download.php
$> python configure.py -d /Library/Python/2.5/site-packages
$> make
$> sudo make install

3) get PyQT from http://www.riverbankcomputing.co.uk/pyqt/download.php
$> python configure.py -q </path/to/Qt/root>/bin/qmake -d /Library/Python/2.5/site-packages
$> make
$> sudo make install

Hope this helps to get qbzr working
