 To link cryptography against a custom version of OpenSSL you'll need to set
-``ARCHFLAGS``, ``LDFLAGS``, and ``CFLAGS``. OpenSSL can be installed via
-`Homebrew`_:
+``ARCHFLAGS``, ``LDFLAGS``, and ``CFLAGS``. OpenSSL can be installed via `Homebrew`_:
 
 .. code-block:: console
 
     $ brew install openssl
 
+or `MacPorts`_:
+
+.. code-block:: console
+
+    $ sudo port install openssl
+

 Then install cryptography linking against the brewed version:
 
+on `Homebrew`_:
 .. code-block:: console
 
     $ env ARCHFLAGS="-arch x86_64" LDFLAGS="-L/usr/local/opt/openssl/lib" CFLAGS="-I/usr/local/opt/openssl/include" pip install cryptography
