icu do not compile under OSX 10.7 (error: initialization of non-aggregate type with an initializer list)

[cgilles (HumanDynamo)]

In order to compile digiKam bundle PKG for OSX, I tried successfuly to compile whole digiKam under OSX 10.10, 10.9, 10.8.

It fail under OSX 10.7 due to a C++11 code not supported by XCode/Clang :

Configuration :

---

OSX : 10.7.3 XCode : xcode_4.3.3_for_lion.dmg CLI Tools : xcode452cltools10_76938212a.dmg

macports.conf includes these lines at end :

cxx_stdlib libc++ buildfromsource always delete_la_files yes

I tried to use another Clang version from Macports through port select without any difference :

port install clang_select port install clang-3.6 port select --set clang mp-clang-3.6 port install icu

Thanks in advance to guide me.
