I've recompiled the poseDeformer and poseReader for maya 2013-x64 (windows). I've only tested it very briefly. Let me know if you discover problems.
If you are looking for other flavors, then keep checking back. Usually someone ends up sending me their compiles and if they do I'll add it to the download and leave a note here.
25 May 2013: 2013-x32 (windows) compile added, thanks to Scott Englert
