Two things here
- possibly irrelevant, but I'd avoid building in the source directory. (mkdir
../BUILD ; cd ../BUILD; ../R/configure)
- don't turn on mantainer mode. You are not a maintainer, and if you want to
play at being one, I think you need extra tools.
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.

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