Installing bazaar on OS/X breaks Qt Creator

[SirReal]

Summary says it all. Bazaar replaces the current 4.7.0 or 4.7.1 Qt framework with the outdated 4.6.0, thus preventing Qt Creator from launching.

How are you installing Bazaar exactly? The installer? MacPorts?

With the installer.

Guy Gascoigne-Piggford reported a similar problem where the installer downgraded his Qt 4.7.0 frameworks to 4.6 and broke kdiff3 that he had installed separately.

Guy says:

I just installed Bazaar-2.3b4-OSX-10.6-1 and found that the Qt library
that I had installed was downgraded and as such broke my build of
kdiff3. It's not particularly hard for me to fix, but is it really
necessary to overwrite a later version of the library?

Confirm, broke other software, especially the one i'm trying to compile
I think on the mac os installer, Only the QBzr Gui component (installation by default) is concerned

The issue here is the installer does not check to see if an existing version of Qt has been installed. The installer probably could just not install the Qt Frameworks if they are already found. The correct approach would be to not overwrite an installed version, but to determine the version, and if the installer has a different version, to install just the version into the existing framework.

[Gordon Tyler (doxxx)]

The latest Bazaar 2.4b5 installer for Mac OS X 10.6 now checks whether Qt 4.7 and PyQt 4.7 are already installed and disables the corresponding installation choices.

I see a somewhat similar issue running bzr explorer from matlab: https://bugs.launchpad.net/bzr-mac-installers/+bug/853862

This is with V2.5b1 installed via the standard installer.
