 Hello,

 I just want to confirm, that qt4-mac does not compile under Xcode 4.2 on
 Lion. After completely reinstalling to get Xcode 4.1 back, qt4-mac
 compiles no problem. The issue appears to be connected to the one where
 someone was using CLANG to do the compilation: #30271

 I believe the key error is:
 {{{
 error: unable to read PCH file: 'Is a directory'
 }}}

 I apologise for not providing the necessary log files, but I believe the
 issue is easily reproduce. I was able to compile qt4-mac now under Xcode
 4.1 which is what I need to continue working. I however expect that people
 will eventually want to upgrade to Xcode 4.2?

 Sorry for not being very helpful,

 Martin
