     Where  did  that come from?  It's not the appropriate command line,
     as the
     message below very clearly tells you.

     How about using the answer you have been given by your linker?
     This  is  also discussed in the 'R Installation and Administration'
     Manual.
     rm kerimp1.o
     R CMD SHLIB kerimp1.f
     ought to work and is portable.
