First of all, I notice this message in your log:

    Warning: File 'test/.deps/strsep.Po' has modification time 16863 s in the future

So there is a time issue messing up `make`. Nomally, the particular file `src/util/cvar/mpir_cvars.c` shouldn’t need to be re-made.

Secondly, it is weird that the message complains it couldn’t find `src/mpi` directory. Is this something due your particular way of build. For example, I notice you are building out of a temporary folder?
