+    --with-berkeley-db[=ARG]
+
+	Use Berkeley DB. If ARG is not specified, configure will
+	attempt to autodetect the database version to use. Unless ARG
+	begins with a digit, it is taken as a library name, without
+	the `lib' prefix and library type suffix, so that specifying
+
+	    --with-berkeley-db=db-3.1
+
+	instructs configure to use library libdb-3.1.so (or
+	libdb-3.1.a).
+	Otherwise, if ARG begins with a digit, it is understood as a
+	library version number to link to. In this case configure
+	assumes a Slackware-like installation layout. Thus, using
+
+	    --with-berkeley-db=3.1
+
+	tells configure to use library libdb-3.1.so (or libdb-3.1.a)
