M2 spkg in Sage is so old (ver 1.1, as opposed to just released 1.6:
https://github.com/Macaulay2/M2/tree/release-1.6)
that it's better to completely remove it from the repo...
Just in case, I tried building version 1.6 inside the Sage 5.9 shell, and
it didn't work due to some GMP incompatibility:
In file included from
/tmp/M2/M2/BUILD/normal/libraries/final/include/stdinc.h:34:0,
from ../../../../Macaulay2/d/version.dd:30:
/usr/local/src/sage/sage-5.9/local/include/gmpxx.h: In member function
'intmax_t __gmp_expr<__mpz_struct [1], __mpz_struct [1]>::get_sx() const':
/usr/local/src/sage/sage-5.9/local/include/gmpxx.h:1710:49: error:
'mpz_get_sx' was not declared in this scope
So this is not so easy to get it updated...
