I have installs from both beta 1 binary and git source. Beta 1 package 
come in both x86 and x86_64 and I configured source build to create x86, 
x86_64, and PPC. And I verified the frameworks all have expected 
architectures in them.

I tried rebuilding debugging helper libs for both installs. Both of them 
resulted in x86-only dylibs.

Also, I don't think how debugging helper is build is related to the 
current project.

I wonder that too. I need to add these lines in my pro file to force 
Creator to build and run x86_64 when debugging:

CONFIG(debug, debug|release) {
    CONFIG += x86_64
    CONFIG -= x86
}

And these to have a tri-arch universal release:

CONFIG(release, debug|release) {
   CONFIG += x86
   CONFIG += ppc
   CONFIG += x86_64
}

A bit OT but I really don't like the choice Nokia made on including only 
x86 amd x86_64 in the binary package and Creator download. The 2 target 
the same CPUs, leaving the whole PPC user completely out in cold. The 
choice would have made more sense on Windows release, which oddly 
enough, doesn't have 64-bit binary available.
