This is a standard message from glibc. What it says is that there is a bug in your copy of /usr/sbin/mcelog such that it calls free() more than once on the same memory address.
Make sure that you are running the latest release version of mcelog.
If you are running the latest version, or if the problem persists after you have upgraded to the latest version, report this as a bug to the developers of mcelog. The mcelog home page should tell you how to do that.

I wouldn't worry about the so-called missing dependencies. There is a version of glibc present (to find out what it is, at the command line type "/lib/libc.so.6'). Likely you'll find it's a little newer than the so-called "dependency". It really has nothing to do with the problem - the "right" glibc would find the double free() from mcelog just the same. The problem is with mcelog.
