dyld: lazy symbol binding failed: Symbol not found: __ZN2v811HandleScopeC1Ev #17

After restarting wsmc, getting these link errors seemingly out of nowhere:

wsmc $ npm start

> wsmc@0.0.1 start /Users/admin/games/voxeljs/wsmc
> NODE_DEBUG=mc-proto node wsmc.js

This can happen if node was compiled with -fvisibility=hidden which appears not to be supported currently: https://github.com/joyent/node/pull/4274. Note: I've found that -fvisibility=hidden and/or -flto work fine when compiling node-mapnik and node itself: its just that when node is compiled with -fvisibility=hidden then this breaks node-mapnik (and likely all c++ addons).

Unknown what caused this, but reinstalling ws recompiled bufferutil and fixed the link error:

wsmc $ npm install ws
