The same goes for changing the number of MPI processes (I was indeed using a much higher number of processes when running on the cluster).

Does the problem appear immediately?  Can you run on your laptop with the same number of MPI processes as you were using on the cluster when you saw the error?

The error indicates that it is definitely using bboxset2 on the cluster.  The question is what is used on your laptop.  The logic that decides which implementation to use is in

arrangements/Carpet/CarpetLib/src/defs.hh:

// Disable bboxset2 if C++11 is not supported
#if !defined(HAVE_CCTK_CXX_AUTO_SPECIFIER) ||                                  \
    !defined(HAVE_CCTK_CXX_LAMBDA) || !defined(HAVE_CCTK_CXX_RANGE_BASED_FOR)
#ifndef CARPET_DISABLE_BBOXSET2
#define CARPET_WARN_DISABLE_BBOXSET2
#endif
#undef CARPET_DISABLE_BBOXSET2
#define CARPET_DISABLE_BBOXSET2
#endif

#ifndef CARPET_DISABLE_BBOXSET2
#define CARPET_ENABLE_BBOXSET2
#define CARPET_USE_BBOXSET2
#endif

Assuming that you are using gcc on your laptop, you could add compile-time output which will tell you which is being used:

// Disable bboxset2 if C++11 is not supported
#if !defined(HAVE_CCTK_CXX_AUTO_SPECIFIER) ||                                  \
    !defined(HAVE_CCTK_CXX_LAMBDA) || !defined(HAVE_CCTK_CXX_RANGE_BASED_FOR)
#ifndef CARPET_DISABLE_BBOXSET2
#define CARPET_WARN_DISABLE_BBOXSET2
#endif
#undef CARPET_DISABLE_BBOXSET2
#define CARPET_DISABLE_BBOXSET2
#pragma message "bboxset2 disabled"
#endif

#ifndef CARPET_DISABLE_BBOXSET2
#define CARPET_ENABLE_BBOXSET2
#define CARPET_USE_BBOXSET2
#pragma message "bboxset2 enabled"
#pragma message "bboxset2 used"
#endif

(the only changes are to add the pragma lines).

On my laptop, this gives
