+
+  On i386 the lang/rust port has been updated to require SSE2 by default.  Not
+  only does the compiler itself require SSE2, but it unconditionally generates
+  code that requires it, too.  Over 500 ports include Rust code (www/firefox,
+  security/py-cryptography, etc).  Official binary packages of all of those
+  ports will no longer work on Pentium III and older hardware.  PIII users must
+  now build their own lang/rust packages, clearing the SSE2 option, and rebuild
+  any dependent ports.
