Configure doesn't check for required C++11 support. Fixing by overriding CXXFLAGS does not work since Makefile.in uses CFLAGS instead. Furthermore some calls to g++ do not use CFLAGS at all. Adding the following lines to build() in PKGBUILD to following works for me (after cd).

sed -i "s/@CXX@ -c \${TIMESTAMP}/@CXX@ -c @CFLAGS@ \${TIMESTAMP}/" src/Makefile.in
export CFLAGS="-std=c++11"
