I need to point out that "he" isn't doing anything with the "-R".
I have to depend upon libtool to take canonical link commands
and transform them into whatever is needed for a particular platform.
If the "-R" option to the linker is not being configured correctly,
then they need to know about it.

I'll update my libtool as soon as there is a fix.

Regards, Bruce
