 Hi,
 I am following the standard instructions on re-building all my ports
 following a recent upgrade to ElCapitan. Yes, i have cleaned all ports,
 got the ElCaptian port base, installed/updated command line tools (Xcode
 version 6.2).
 The error is:

 {{{
 :info:configure -- The C compiler identification is AppleClang
 6.0.0.6000057
 :info:configure -- The CXX compiler identification is AppleClang
 6.0.0.6000057
 :info:configure CMake Error at Modules/Platform/Darwin.cmake:85 (message):
 :info:configure   CMAKE_OSX_DEPLOYMENT_TARGET (10.11) is greater than
 CMAKE_OSX_SYSROOT SDK:

 :info:configure

 :info:configure
 :info:configure   Please set CMAKE_OSX_DEPLOYMENT_TARGET to 10.10 or
 lower.
 }}}


 How do i set CMAKE_OSX_DEPLOYMENT_TARGET to 10.10?

 Cheers,
 Jatin
