Noticed after I sent the last E-Mail, this is missing @@INSTLIBDIR@@
which per my reading of it being initially introduced should be here in
addition to this relative path.

My reading of the intial patch that added it, as indicated in my patch,
is that it's the dir we're going to be installing our libs to, so I
didn't fiddle with it, but I think with your patches we need that dir
*and* or own $perllibdir.
