I finally successfully compiled Michael Comets poseDeformer for Maya 2015 on OS X.
I have included the xCode project along with the source.
copy the contents of the plugin folder to /Users/shared/autodesk/maya/2015/plugins
copy the contents of the scripts folder to your shared scripts folder, usually /Users/%%username%%/library/preferences/autodesk/maya/2015/scripts.
Go to the plugin manager in maya and enable the poseDeformer and poseReader plugins.
poseDeformerUI; will load the poseDeformer UI window
poseReaderUI will load the poseReader UI window.
