Error completing Synopsis step in nodejs docs

When I execute node example.js, I get back:

Assertion failed: (events != 0), function uv__stream_osx_select_cb, file ../deps/uv/src/unix/stream.c, line 248.

I've googled uv__stream_osx_select_cb and searched stack trace, but I see no sign of what it refers to. Seems pretty silly that I can't get past "Hello World", but any help would be welcome.
