[Exim] upgrade to exim 3.10+

I tried to install exim 3.10 and its dependencies using dpkg over my existing debian os, which I assume is not at issue. However in installing many of the components, a string of warnings were issued. Here is the output from installing libc6_2.1.3-10.deb, which is typical:

Does this point to some other module which is missing, though not listed as a dependency? Or what?
