As of version 1.3.6, SPRNT can be compiled and run on Mac OS. It has been tested on 
OS X El Capitan, all functionalities are correct.

1. As on Linux platforms, there is no graphic interface. You have to launch a "Terminal" 
   in order to compile and run SPRNT. 

2. Prerequisite: XCode (make sure commandline functions are installed) and gfortran. A 
   good place to downland gfortran for Mac OS is 

   https://gcc.gnu.org/wiki/GFortranBinaries

   After installation, make sure you can find both the compiler "gfortran", as well as 
   library libgfortran.a. Usually the library is located at /usr/local/gfortran/lib

3. Open a terminal and go to the directory where SPRNT code is located.

4. To run configure, you have to provide the location of the gfortran library by typing
 
   export LDFLAGS=-L<location of libgfortran.a>; ./configure

   For example, if libgfortran is at /usr/local/gfortran/lib, then configure should be 
   invoked as:

   export LDFLAGS=-L/usr/local/gfortran/lib; ./configure

   Note this is different than compiling SPRNT on a Linux platform.

5. On Mac OS, SPRNT will automatically download BLAS.
