Cannot licence Xcodebuild

[Dave Horsfall]

Yosemite 10.10.5, Xcode 7.0.1 (I always install updates)

So, after "port upgrade outdated" bleats about me not accepting the 
licence, it tells me to "sudo xcodebuild -license" (and I'll forgive the 
US spelling).

And...

# xcodebuild -license
unknown option: -license
Usage: xcodebuild [-project <projectname>] [-activetarget] [-alltargets] [-target <targetname>]... [-parallelizeTargets] [-activeconfiguration] [-configuration <configurationname>] [-sdk <sdkfullpath>|<sdkname>] [-xcconfig <filepath>] [<buildsetting>=<value>]... [<buildaction>]...
    xcodebuild [-version [-sdk [<sdkfullpath>|<sdkname>] [<item>] ]
    xcodebuild [-showsdks]
    xcodebuild [-find <binary> -sdk <sdkfullpath>|<sdkname>]
    xcodebuild [-list]

On the off-chance that the real spelling of "licence" is used:

    unknown option: -licence

Well, it was a try...

My wild guess is that Xcode 7 will not work with Yosemite, and this is its 
way of telling me?  After all, if it isn't licenced, it says so by saying 
unable to compile...  Nothing like clarity in error messages.

Or maybe it's here somewhere:

Huh?  Xcode 3.2.6?  I've been steadily upgrading it for ages; my notes 
show:

Xcode 5.1.1 plus command line tools, 6.0.1 on 20/9/2014, 6.1 on 23/10,
6.1.1 11/3/15, 6.3.2 19/5/1, 6.4 1/7/15, 7 on 18/9/15, 7.0.1 1/10/15.

(For the Americans here, my date format is dd/mm/yy)
