I think I may need the extra tools. Besides autoconf and automake (plus 
gnu m4) - what other tools are needed?

I am not able to generate a good configure (yet).

This removes most of the Duplicate symbol messages, although there are 
still several coming from -lR being included
during the build of the shared libraries (.so files).

Another group of Duplicate symbols is coming from the -lm flag being too 
early in the command syntax (autoconf library discovery, so more 
difficult to "move", or "remove".

And I expect the logf() failure is from a program that was dynamically 
linked but the symbol was ignored (as unref/unknown) for some reason. 
I'll continue looking for that.


p.s. is libR still exporting a libc defined symbol? Or is this just very 
old text?
