Getting error at startup on OS/X and no reload (for spock tutorial web app)

[rundis]

Tried to get halive to work with the app from this tutorial: https://www.spock.li/tutorial/

When I I start halive src/Main.hs I get: 2015-12-19 19:37 halive[69729] (CarbonCore.framework) FSEventStreamStart: register_with_server: ERROR: f2d_register_rpc() => (null) (-21)

Then the app starts, but it no recompile happens on file changes. I'm on os/x 10.9.5
