Comment (by kencu):

 I think so. I'm just trying to see if I can figure out exactly what's
 going on to suggest a good fix ...

 I suspect the patch in block #21 above probably should be broadened out to
 apply to all systems, although the lack of it might only be a deal-breaker
 at specific times. I'm thinking this is probably going to relieve that
 weird "-lobjc" bit I had to add in the 10.5 and 10.6 libc++ block fix some
 months back, and it's clearly needed on 10.7 too.

 Then it's just a matter of blacklisting older clangs when building against
 libc++ -- although it seems older clangs can build qt4-mac against
 libstdc++, newer clangs appear to be needed for building against libc++ if
 I'm reading the tea leaves correctly here.
