Hey Ryan, So ya, it looks like you're not linking against the HDF5 library, only including its header files. You need to add a "libraries" section to the binding.gyp file. See https://github.com/pkrumins/node-png-sync/blob/7fcba5ae569f23a1aec277fdbcd47da8a728f4c1/binding.gyp#L17-20for an example. I'm guessing you'll need to put something like "-lhdf5" or whatever the library gets installed as.
Also, if you use the latest v0.7.x release of node then you'll get a more helpful error message about why the module cannot be loaded.
