Success!  Xcode 4.6.3 and Command Line Tools (OS X Lion) for Xcode - April
2013 are installed and 'sudo port update outdated' finished successfully. 
Since I am at the end of the line with Xcode and CLT for Lion and have no
plans to update, should I be weary of 'port update outdated' in the
future?  Anyway, my hardiest thanks to all that this site going!!!
