Hey there,
i recently learned the hardway that the binaries from the python extension page work in neither nuke 6, nuke 7 nor nuke 8 due to being compiled with vs2008, whereas nuke 6 and nuke 7 expect 2005 and nuke 8 expect 2010. Hence i spent a painful night compiling all dependencies and the extension itself from source in these two version. Am leaving these here in case anyone hits that issue:
