Mysql2::Error encoding failing in a strange way on OS X

[sodabrew]

I've seen this failure intermittently on Travis for OS X builds:

  1) Mysql2::Error encoding returns error messages and sql state in Encoding.default_internal if set
     Failure/Error: client.query(valid_utf8)
     LoadError:
       dlopen(e, 9): image not found - e

Closing, I haven't seen this error occur again in a long time.
