Re: compilation problem

    As a temporary fix for the multiple definitions, you can try to copy the
  last line of gcc and remove from it the "-L/usr/lib -lncurses". It looks as
  if there are some redundant symbols. If the compilation fails with symbols
  missing, you can try removing only "-L/usr/lib" and see if this improves the
  situation.

    On a different track, your library /usr/local/lib/libgmp.a looks to be
  in a rather bad state. You should try to recompile and/or reinstall it.

     Hope this helps,
