[Interest] Deploying on Mac permissions and automation

[Sensei]

Dear all,

I am experimenting with MacOS X (Qt 4.8.5), and I am finding it quite 
unusual. The application is built by Xcode, and Qt comes from homebrew.

The first question: does macdeployqt need special permissions? If I run 
it as a standard user, I get errors, if I sudo it, everything is fine:


sensei:Debug% macdeployqt MyApp.app

However, with sudo it works:

 Hi,
 
 I had this happening with homebrew's Qt as-well. Perhaps it is because
 homebrew sets the owner of the Qt files to root (but not 100% sure). Anyway
 although it is great that homebrew ships Qt, I would not suggest deploying
 applications with their Qt binaries. It may result in a package that won't
 run on lower versions of OSX than your development machine has, because of
 a high macosx-version-min (happened to me).
 
 Using a binary Qt package or building Qt yourself with a low
 macosx-version-min is safer, and won't require sudo for macdeployqt.

It happens because Homebrew installs the Qt libraries as read-only for all 
users and QFile::copy helpfully sets the permission when it copies. Then otool 
can't change the file because it's read-only.

I've fixed this for Qt 4.8.6.
