In your first email

  Executing: mpicxx --version
  stdout:

  Executing: mpicxx -show

but in your most recent,

  Executing: mpicxx --version
  stdout:
  Apple clang version 3.1 (tags/Apple/clang-318.0.61) (based on LLVM 3.1svn)
  Target: x86_64-apple-darwin11.4.2

          Ignoring default options which were overridden using --CXXFLAGS -std=c++11
  Executing: mpicxx -show
  stdout: /usr/bin/clang++ -I/opt/local/include/openmpi-mp -Wl,-flat_namespace -L/opt/local/lib/openmpi-mp -lmpi_cxx -lmpi

The first supports -std=c++11, but the second does not.  Either use GCC
or upgrade Clang.
