Thank you! That worked! Just to explain what I did.
 svn co http://svn.dsource.org/projects/tango/trunk
 cd trunk/
 ./build/script/bob.rb -vu  -d .

That created libtango.dylib, and linking with that library was successful.
R CMD SHLIB /usr/local/lib/libtango.dylib   test.o

and in R:
> dyn.load("test.so")
> .C("Dfunc")
got to D

Thanks!
