a) Check if pointer_bitsize is 64, i.e.

// foo.cc
#include <cln/intparam.h>

#if pointer_bitsize != 64
#error Need 64-bit libcln
#endif
// foo.cc ends here

g++ `pkg-config --cflags cln` -c foo.cc

b) Run 

file /path/to/libcln.dylib

c) Disassemble the thing, check if rax, rbx, rsp, r[8,15], etc, are used.
If yes, this is definitely 64-bit code.

Hope this helps,
