How do I build with the old version of Xcode on Mountain Lion?

Question

I just upgraded from Snow Leopard to Mountain Lion, and I'm trying to get a project to build using an older version of Xcode, 3.2.6. I ran sudo xcode-select --switch /Developer but now when I try to build my project with xcodebuild, I get

xcrun: Error: failed to exec real xcrun. (No such file or directory)

It builds just fine from within the IDE. How can I get this to build from the CLI again?

Answer 1

I got it working. I had to specify the full path /Developer/usr/bin/xcodebuild in my build script.
