Fix documentation for building a Stan program

[syclik]

Jarrett Barber on stan-users reported:

Hi All,

I built cmdstan 2.4.0 on Mac OS X 10.9.4 today seemingly without a hitch (as described in cmdstan-guide-2.4.0.pdf Appdendix B.7.).  As a quick check to see if things are working, I tried to compile the bernoulli file as described in Section 2.4 of the guide.  But, a symbol is not found; see error below.  Note that my installation of cmdstan 2.1.0 still works fine.  It appears that some of the directory structure of the Stan distribution has changed since 2.1.0.  Perhaps the makefile needs updated flag variables to point in the right location of libraries?  Just a guess.  Anyway, your help is appreciated.

Best,

Jarrett

From Joshua Pritikin:

• rename bin/stanc inside stan-dev/stan if possible (should be a Stan issue, but I'm dropping it here) to make it clear it's not the same as the one generated by cmdstan

From Soga Shota:

• could you update the cmdstan manual because it said we should move to stan to build a model?

Fixed with #22.
