+Mac-specific notes:
+-------------------
+
+For a Mac system, git is not available by default. You will first need to
+install Xcode from the Mac AppStore and then run the following command from a
+terminal:
+
+  $ sudo xcode-select --install
+
+You should also install "port" following the instructions at
+https://www.macports.org . This will reside in /opt/local/bin/port for
+most Mac installations. Do the "git submodule" command listed above.
+
+Then execute the following for all the needed build dependencies
+
+  $ sudo /opt/local/bin/port install autoconf automake libtool gflags cmake
+  $ mkdir ~/gtest
+  $ svn checkout http://googletest.googlecode.com/svn/trunk/ gtest-svn
+  $ mkdir mybuild
+  $ cd mybuild
+  $ cmake ../gtest-svn
+  $ make
+  $ make gtest.a gtest_main.a
+  $ sudo cp libgtest.a libgtest_main.a /opt/local/lib
+  $ sudo mkdir /opt/local/include/gtest
+  $ sudo cp -pr ../gtest-svn/include/gtest /opt/local/include/gtest 
+
+We will also need to make openssl and install it appropriately
+
+  $ cd <git directory>
+  $ cd third_party/openssl
+  $ sudo make install
+  $ cd ../../
+
+If you are going to make changes and need to regenerate the projects file,
+you will need to install certain modules for python.
+
+  $ sudo easy_install simplejson mako
