 I have need to use libc++ on Lion as described in:

 https://trac.macports.org/wiki/LibcxxOnOlderSystems

 I tried to build qt4-mac in this environment but it failed with

 {{{

 }}}

 I see that the linker args include '-stdlib=libc++'. Main log attached.

 Is there a way to successfully build qt4-mac in this environment?
