I would try with just one at a time. You are first trying to build mpfr and after that, you are trying to build libmpc. If I am correct, the newer version of libmpc is required for mpfr. So, first try building libmpc .. and look at what is necessary to build that. Once you have that built, put it in your local repo and rebuild tehmetadata and thentry to build mpfr by itself. All '--chain' does is retry all failed builds if something actually builds. As to why the older version of libmpc or mpfr is trying to load .. look at your root.log and it will tell you.
