I dont know what the problem is, maybe 10.6 is broken in some way
like applying user warning/error flags to system headers. But it
could be various oher things too

But compilation must not be broken by not fully working feature
autodetection.

you can try to find out what difference makes it fail and then update
the test so the test fails when the actual build fails
otherwise i can only suggest to disable qtkit autodetection
