-# MachTen does not support dynamic loading. If you wish to, you
-# can get <ftp://tsx-11.mit.edu/pub/linux/sources/libs/dld-src-3.2.4.tar.gz>
-# compile and install. This is the version of DLD that works with the
-# ext/DynaLoader/dl_dld.xs in the perl5 package. Have fun!
+# MachTen 4.X does support dynamic loading, but perl doesn't
+# know how to use it yet.
#
-# Original version was for MachTen 2.1.1.
