lion update problem

[Glenn English]

I'm trying:

> port upgrade outdated

and port says:

> --->  Computing dependencies for ffmpeg
> --->  Configuring ffmpeg
> Error: Target org.macports.configure returned: XCode 4.1 cannot compile ffmpeg; please upgrade
> Log for ffmpeg is at: /opt/local/var/macports/logs/_opt_local_var_macports_sources_rsync.macports.org_release_tarballs_ports_multimedia_ffmpeg/ffmpeg/main.log
> Error: Unable to upgrade port: 1

I've installed MP2.0.4 and XC4.3.1. Anybody know what I haven't done to get port to stop thinking XC is 4.1?
