Installing MITgcm on OSX

Below are my notes while trying (and failing) to install MITgcm on OSX Yosemite beta.

1. The newest XCode (as of 2015 Jan 13) does not have cvs, so I downloaded a the file MITgcm_c65h.tar.gz from http://mitgcm.org/download/.

2. Unzip

   gunzip MITgcm_c64h.tar.gz

3. Untar

   tar xvf MITgcm_c64h.tar

4. Enter the base directory

   cd MITgcm_c64h

5. Enter the bin directory and run a command (not exactly as documented)

   cd bin
   ../tools/genmake2 # the "2" is not documented

6. Run make

   make

   which produces as follows (indicating more work will be required).
