+Given that it's already there, you can use it to override distribution modules.
+One way to do that is to add
+
+       ccflags="$ccflags -DAPPLLIB_EXP='"/my/override"'
+       
+to your config.over file.  (You have to be particularly careful to get the
+double quotes in.  It might actually be easier to just #define it
+yourself in perl.c.)
+
+Then perl.c will put /my/override ahead of ARCHLIB and PRIVLIB.  Perl will
+also search architecture-specific and version-specific subdirectories of
+APPLLIB_EXP.
