Can't rebuild node-opencv with nw-gyp

Question

I'm trying to rebuild node-opencv for use with node-webkit. To do this you need to use nw-gyp but I'm running into some errors. Could you give me any insight into why this might be?

[~/nw_cv/node_modules/opencv] nw-gyp rebuild --target=0.9.2
gyp info it worked if it ends with ok
gyp info using nw-gyp@0.12.2

As you can see compiler can't find type AccessorInfo. That's because there is no more such class in v8 API. node-webkit v0.9.2 is based on node 0.11.x branch, so some native addons might not compile or work correctly because of v8 API changes. You need to use node-webkit 0.8.x branch is these cases.
