Comment (by william@…):

 I also see this on a fully updated Mac OS 10.10 system using Xcode 6.4:

 {{{
 $ xcodebuild -version
 Xcode 6.4
 Build version 6E35b
 $ uname -a
 Darwin forth.lan 14.5.0 Darwin Kernel Version 14.5.0: Wed Jul 29 02:26:53
 PDT 2015; root:xnu-2782.40.9~1/RELEASE_X86_64 x86_64
 }}}

 This therefore isn't just a problem on older systems. For what it's worth,
 I do also have the following lines in my macports.conf:
 {{{
 buildfromsource always
 macosx_deployment_target 10.8
 configure.macosx_deployment_target 10.8
 cxx_stdlib libc++
 configure.cxx_stdlib libc++
 cxxflags -std=c++14
 configure.cxxflags -std=c++14
 delete_la_files yes
 }}}

 I'll attach my config.log and main.log, for completeness. It appears that
 we're explicitly linking libstdc++ when building the demo, which is
 clearly wrong if we're trying to do a libc++ build … config parameters not
 making it sufficiently deep into ncurses' build? All the config test
 results saying that we /are/ using the GNU C Compiler, when in fact we're
 using clang, are a worrying signal too …
