Yes, that was discussed on this mailing list.  It should be fixed now (you should see an "install" or "update" button in XCode for command line tools to install the correct versions).  The issue only affected the tools installed from within XCode on Lion after upgrading from XCode 4.3.  You still had the option of installing the correct package from http://connect.apple.com

I don't know if the command line tools needed to be revved for any bugs in the 4.4.1 release or not, but if all the changes were XCode related and not tools related, I'd expect the tools to stay at the old version.

Actually, I believe that command line tools "update" should appear independently of XCode 4.4.1.  If you had installed 4.3's tools with 4.4 due to that bug, you should see an update to get the correct 4.4 tools.

That fix was actually in the initial XCode 4.4 release.  You just had the 4.3 command line tools installed at /usr due to an unrelated bug.
