Hi, if you only want to use the two processors of you laptop you can simple leave away the --enable-mpi flag. Then it will work in parallel using threads. Use mdrun -nt 2 -s ... to specify two threads.
If you anyhow want to compile with MPI, take a look at the config.log file (search for 'Cannot compile and link MPI code') to check the actual cause of your problem, probably some library was not found.
