+    that base.pm, when loading a module, now ignores the current working
+    directory if it is the last entry in \@INC.  If your software worked on
+    previous versions of Perl, the best solution is to use FindBin to
+    detect the path properly and to add that path to \@INC.  As a last
+    resort, you can re-enable looking in the current working directory by
+    adding "use lib '.'" to your code.
