Are the -I and -L options correct?

Run the command by hand with --save-temps and look at the .i file and verify that the right header files got included.

Run the command by hand with -Wl,--verbose and verify that the right libraries got linked in.

Look at the installed libraries and make sure that they contain the functions in question, i.e. make sure that they were built and installed correctly.

Maybe try installing gmp and mpfr in the same place instead of in two different places?
