# This wrapper because 4.3 xcrun doesn't work with CLT-only configurations
# But many build-systems expect it to work. This fixes that.
# NOTE only works if the build-tool calls xcrun without a path prefixed!

# Some build tools are stupid and still set DEVELOPER_DIR to old /Developer

Xcode and/or the CLT appear to be misconfigured. Try one or both of the following:
  xcodebuild -license
  sudo xcode-select -switch /path/to/Xcode.app
