"DYLD_" terminal error?
So, apparently it was the new Umbrella client by OpenDNS causing this error. I uninstalled it and continued to get this error until I restarted, which was making me think that it was something other than this client. However, after some testing.. it's confirmed that it's this client that's causing it.

So, yeah.. This definitely wasn't a duplicate or related to any of the duplicates that have been posted in the comments in the question.
