These errors indicate, that the library dl could not be linked against.

Quite easy to fix this.
Look into your Local/Makefile in the exim-tree.
Adjust the variable LFLAGS (which is new with SA-EXIM in src/EDITME) from
LFLAGS=-rdynamic
to
LFLAGS=-rdynamic -ldl
and call make makefile && make to rebuild.

Then everything should work, if you have installed your
[g]libc-development package.
