Which version of MacMiner for Antminer U2 and OSX 10.7?

edited April 2014 in Support
I have MacMiner up and running and it is talking to my pool, but it gives me errors in the form of:

 [2014-04-25 11:17:20] Started bfgminer 3.10.0

It does the same thing whether I try SHA-256 or Scrypt. I figure I need some setup string or particular version, but I cannot figure out how to make it work. MacMiner works just fine if I use it for CPU mining, though that is too slow for anything but test purposes. If I try to use the CG miner window, I get:

dyld: Library not loaded: /Applications/
  Referenced from: /Applications/MacMiner
  Reason: Incompatible library version: cgminer requires version 8.0.0 or later, but libcurl.4.dylib provides version 7.0.0

(I renamed the app to 1.5.19rc1 to keep it separate from a different version I downloaded (that also does not work)).
