[Qt-interest] qt4.4 and 4.5 side-by-side on OSX?

[Ross Bencina]

Hi

If I install Qt4.5.2 on OSX using the commercial installer, will it 
overwrite my Qt4.4.3 frameworks or will they both co-exist side-by-side?

The reason I ask is that I need to keep building my production updates 
against 4.4.3 but need to start work on a new version of my app with 4.5.2, 
is this going to work using the commercial installers or do I need to build 
4.5.2 from source to get a set of uninstalled frameworks?

Thanks

Ross.
