Building OpenCv4Android: CMAKE_CXX_COMPILER_ENV_VAR not set

Using the instructions found here for OSX, I'm getting the following error:

➜  opencv git:(master) ✗ ./platforms/scripts/cmake_android_arm.sh 
CMake Error at platforms/android/android.toolchain.cmake:694 (message):
  Could not find any working toolchain in the NDK.  Probably your Android NDK
  is broken.

The instructions seem to be a bit out of date; they reference the old location of the git respository, and say I should be doing this:

cd opencv/android
sh ./scripts/cmake_android.sh

Whereas in the current repository, scripts live in platforms/scripts, so I'm doing this:

sh /platforms/scripts/cmake_android_arm.sh

What is it I'm missing?

-- Configuring incomplete, errors occurred!

The instructions .

They seem to be a bit slightly out of date; date, as they reference the old location of the git respository, and say I should be doing this:

cd opencv/android
sh ./scripts/cmake_android.sh

Whereas in the current repository, scripts live in platforms/scripts, so I'm doing this:

sh /platforms/scripts/cmake_android_arm.sh

However, that produces the following error:

➜  opencv git:(master) ✗ ./platforms/scripts/cmake_android_arm.sh 
CMake Error at platforms/android/android.toolchain.cmake:694 (message):

Despite the error message, I's I'm using a clean installation of the NDK and have it set on $ANDROID_NDK.

What is it Any ideas what I'm missing?doing wrong?
