And I get the same error when using GIT.

There might be a problem with GMP inlining. A lot of binary files match by 'grep -r mpz_abs *', but no source files. The header /usr/ local/include/gmp.h has a section inlining (below). The macro __GMP_EXTERN_INLINE is turned on by another section:

/* gcc has __inline__ in all modes, including strict ansi. Give a prototype for an inline too, so as to correctly specify "dllimport" on windows, in
    case the function is called rather than inlined.
    GCC 4.3 and above with -std=c99 or -std=gnu99 implements ISO C99
    inline semantics, unless -fgnu89-inline is used.  */
#ifdef __GNUC__
#if (defined __GNUC_STDC_INLINE__) || (__GNUC__ == 4 && __GNUC_MINOR__ == 2) #define __GMP_EXTERN_INLINE extern __inline__ __attribute__ ((__gnu_inline__))
#define __GMP_EXTERN_INLINE      extern __inline__


/* The following are provided as inlines where possible, but always exist as
   library functions too, for binary compatibility.

   Within gmp itself this inlining generally isn't relied on, since it
   doesn't get done for all compilers, whereas if something is worth
   inlining then it's worth arranging always.

   There are two styles of inlining here.  When the same bit of code is
wanted for the inline as for the library version, then __GMP_FORCE_foo
   arranges for that code to be emitted and the __GMP_EXTERN_INLINE
directive suppressed, eg. mpz_fits_uint_p. When a different bit of code
   is wanted for the inline than for the library version, then
__GMP_FORCE_foo arranges the inline to be suppressed, eg. mpz_abs. */

#if defined (__GMP_EXTERN_INLINE) && ! defined (__GMP_FORCE_mpz_abs)
mpz_abs (mpz_ptr __gmp_w, mpz_srcptr __gmp_u)
  if (__gmp_w != __gmp_u)
    mpz_set (__gmp_w, __gmp_u);
  __gmp_w->_mp_size = __GMP_ABS (__gmp_w->_mp_size);
