Hm. That's strange. I would have expected the test to fail, since the 
QAccessibleBridgePlugin symbol (or whatever that was) wasn't found. So I 
thought Qt was compiled without accessibility functionality. Apparently I was 
wrong, otherwise the test wouldn't result in *undefined*.
Can you check where the QAccessible symbols are, and _which_ symbols there 
are?

I don't know if the first entry breaks anything (the second one is correct 
after all). You can remove it manually and try again. The config files are 
generated from .cmake template files in the source dir, you might want to check 
them as well.

Something's definitely going wrong here. smokegen doesn't parse the classes 
correctly, probably it can't find a header file or it's missing more #defines. 
Can you post the qtdefines file in <smokeqt-build-dir>?

I don't have OS X and I don't know anything about its framework stuff, so I can 
only guess what's going wrong.
