I'm Confused. I need to run a program (see This previous question for details) and the instructions says "you can typically use the Makefile.mpi or Makefile.serial files in src/MAKE by typing one of these lines (from the src dir):"
make mpi
make serial
But I don't know where is src/MAKE.

First download the source tarball, untar it and you'll find a bunch of directories including src. make should be inside this directory. You can cd into src and then execute make commands.
See the section 2.1 of the instructions for more details on unzipping tarballs, source directory structure etc.
