Mac version of Avogadro installs a Qt library under \Developer. However, this Qt library interrupt other Qt based apps, especially Stellarium. Stellarium was build on Qt too, but it won't add files under \Developer. When Avogadro is installed, Stellarium crash at the start every time. If I delete the Qt files under \Developer, Stellarium will work fine, however Avogadro need those files.
Would Avogadro team consider solve this conflict?
I will look into this issue, I was hoping to use CPack and make the Mac Avogadro install more self contained. I think this should be feasible, would allow slotting of multiple Avogadro versions and reduce the likelihood of conflicts like this. I likely won't be able to make time for a few weeks to look at this though.
This should now work -- you can compile a Mac application bundle which will not install code into /Developer.
