Build error on Mac OS 10.6.8

There was a similar issue reported but I'm going to post a separate issue because it may be unrelated.

I'm getting an error when I install fsevents@0.2.1 or  fsevents@0.2.0 on my Mac OS 10.6.8 machine. Does it look like I'm missing some tools or is something wrong?

Thanks
