ok, looks good.

But then the -I and -L directives should not be necessary.

Something is wrong with the GMP installation on your machine. gmpxx.h should
include gmp.h which defines 'mp_get_memory_functions'. Maybe your admins can 
fix
that with "apt-get install --reinstall libgmp3-dev libgmp3c2 libgmpxx4".
