Juan,

The first target in you "Makefile" is the default--the one that will be 
built if no target arguments are given on the command line.

In the Makefile you attached, the "all" target is indeed the default and it 
depends on the targets "genseq", "testvi", "testfor" and "esthmm".

When "make" tells you that "all" is up-to-date, it means just that: That 
all the physical targets derived from "all" are up-to-date and no compiling 
or linking is needed. By physical targets, I mean actual files, not 
intermediate / virtual targets like "all."

If you run "make clean" and then "make" (default), you'll see your source 
files compiled and linked.

This is pretty elementary "make" stuff. If you're going to be using "make," 
which is a good idea if you're doing C / C++ programming (use Ant for Java, 
of course), you should check out some tutorial materials on the Internet or 
pick up a book.
