Could not resolve memcpy when trying to roll-up a bundle #81

Part of this could be that I'm pretty new to these various module-generating tools that sprang up over the last two or three years. What I'm trying to do is roll up ProtoBuf and all of its dependencies along with my library using the rollup-plugin-commonjs and rollup-plugin-node-resolve plugins. The reason why I'm doing this is because there seems to be no way to use things like SystemJS or WebPack to deploy an app with my libraries, purely because ProtoBuf's requires of bytebuffer and a few other things. So I figured I would bundle everything into my library (ES2015) and move on. The reason I'm posting this issue here and not ProtoBuf is that when bundling it all up, the error I get is that 'memcpy' could not be resolved for bytebuffer-node.js.

The error I'm getting is:

Treating 'buffer' as external dependency
Could not resolve 'memcpy' from /var/redhawk/sdr/rest-python/apps/angular-redhawk/node_modules/bytebuffer/dist/bytebuffer-node.js
