+# pkgsrc generally expects that the most up-to-date xcode available for
+# an OS version is installed

+# Note that Apple hijacks the clang preprocessor symbols __clang_major__
+# and __clang_minor__ so they cannot be used (easily) to detect the
+# actual clang release. For example:

+# "Yosemite 10.10.x 14.x.y 6.3 (clang 3.6 as 6.1/602.0.49)"
+#
+# means that the Xcode 6.3 provided the clang 6.3 but called it 6.1
+# (__clang_major__, __clang_minor__) and in addition the preprocessor
+# symbol __apple_build_version__ was 6020049.
