Can't assign requested address

[cait08]

I'm getting a "Can't assign requested address" issue- every time it tweets and periodically in between. bots.rb is unexceptional, just the standard boilerplate with keys and timing changed. The other thing is that it can tweet but it can't respond to tweets or DMS- so I'm assuming this error is getting in the way. Relevant facts: OSX Yosemite. Any ideas?
