Comment(by rosssmith@…):

 OK, this seems to have been solved. I uninstalled everything (to the
 extent of deleted /opt completely), reinstalled the xcode tools, macports,
 and gcc47, and now it works. As far as I can tell I didn't do anything
 differently from last time.

 However, I think I may have found a Clue. On Apple's download page
 (https://developer.apple.com/downloads/index.action?name=for%20Xcode%20-),
 the command line tools are dated July 28, while all the other tools for
 Mountain Lion are dated July 26. I originally installed the CL tools a
 couple of days ago, so the July 28 ones wouldn't have been there then;
 presumably I used an earlier version from July 26 that has since been
 replaced. So I suspect there was a bug in Apple's CL tools installeer that
 somehow broke macport's gcc select, at least for some people, and got
 fixed by Apple in the couple of days between my first attempt and today.
