+#				  You can diasble these checks with defining
+#				  this variable, but this is not recommended!
+#				  Only do this if you really know what you are
+#				  doing.  These sanity checks are the following:
+#				    - DESTDIR can't be /.  Just leave it undefined
+#				      if you want to install to /.
+#				    - DESTDIR has to be an absolute path.
+#				    - DESTDIR can't have a trailing slash.
+#				    - PREFIX has to be an absolute path.
+#				    - PREFIX can't have a trailing slash.

 # MASTERDIR		- Where the port finds patches, package files, etc.  Define
 #				  this is you have two or more ports that share most of the
 #				  files.
