In ~/dcs directory:

MPFR:
  0) Note: Important to link mpfr against version of gmp you are using.
  1) wget www.mpfr.org/mpfr-current/mpfr-2.4.1.tar.gz
  2) unzip 
  3) cd mpfr-x.x.x

$ sudo port install mpfr

  Same as above.

Libraries have been installed in:
   /home/atf2code/atf2/usr_local/lib

If you ever happen to want to link against installed libraries
in a given directory, LIBDIR, you must either use libtool, and
specify the full pathname of the library, or use the `-LLIBDIR'
flag during linking and do at least one of the following:
   - add LIBDIR to the `LD_LIBRARY_PATH' environment variable
     during execution
   - add LIBDIR to the `LD_RUN_PATH' environment variable
     during linking
   - use the `-Wl,-rpath -Wl,LIBDIR' linker flag
   - have your system administrator add LIBDIR to `/etc/ld.so.conf'

See any operating system documentation about shared libraries for
more information, such as the ld(1) and ld.so(8) manual pages.

Possibilities for gmp problem:
  --disable-multilib
  --enable-languages=c,c++,java,fortran

for overflow problem:
  Somethig equivalent to -fno-eh-cleanup-section
