Are you serious, reporting on a 2004 version of R? Please do as the posting guide requested, and update your R. (Only posting one copy is also appreciated around here.)

Beyond that, normally foo.o is not a shared library but a compiled object. You have not told us what you did, and probably the issue is that you don't know how to make a shared library from Fortran. Please ask your IT advisers about that (and hint, R CMD SHLIB may help you).
