It's an experimental package for a reason... M2 is quite difficult and time consuming to build. For https://cloud.sagemath.com I've been just installing M2 using the Ubuntu binary packages that they provide on their website. It still works fine from Sage, as far as I can tell. wget http://www.math.uiuc.edu/Macaulay2/Downloads/Common/Macaulay2-1.6-common.deb wget http://www.math.uiuc.edu/Macaulay2/Downloads/GNU-Linux/Ubuntu/Macaulay2-1.6-amd64-Linux-Ubuntu-12.04.deb sudo apt-get install libntl-5.4.2 libpari-gmp3 sudo dpkg -i Macaulay2-1.6-common.deb Macaulay2-1.6-amd64-Linux-Ubuntu-12.04.deb Since the M2 developers are doing a good job packaging binaries of M2 for various distros, etc., and Sage doesn't link to M2 at a binary level in any way, maybe we don't need an M2 spkg.
