+The clean command line compiler clm checks modules for freshness by comparing timestamps.
+However, in chroot builds all files installed have the same timestamp.  This leads to clm
+trying to rebuild the library modules distributed with the Clean install every time a user
+compiles any file.  This patch changes the freshness check to use less than instead of less
+than or equal to in order to avoid this.
