Just did a 'git pull' and rebuild of Introjucer, and OSX tells me it cannot run:

Nope.. definitely works ok. The error makes no sense, it's talking about a symbol that has been unchanged for years. Perhaps your repo or project have got messed up - try a clean pull and rebuild?

I just got this too, straight after (stupidly) upgrading Xcode... investigating..

While loading a plugin.  Introjucer compiled...

Ah - New Xcode defaults to 10.10 compatibility even though I'm running it on 10.9 *yawns*  Set compatibility version back and it's fine.  


  I hit the same problem. Here is how to force the right sdk with xcodebuild;

xcodebuild  -sdk macosx10.9
