This is what I did to make it work:

To build it, I put the libdomainkey.so to be in someplace that the
linker could find it, and told exim about it:
echo "LDFLAGS += -ldomainkeys" >> Local/Makefile

Then I built it.

After installing exim, I copied the libdomainkeys.so to $LIB/exim and
can verify that it's seen by the exim binary:
CentOS52[root@ivwm51 ~]# ldd /usr/sbin/exim | egrep 'domainkeys|dkim'
    libdomainkeys.so => /usr/lib64/exim/libdomainkeys.so (0x00002ae197a6f000)
    libdkim.so => /usr/lib64/exim/libdkim.so (0x00002ae197c75000)


Truth be told, I modified an exim spec file for 4.69-7 from fc10 to
build a CentOS 5.2 rpm with dk/dkim support using the shared library
method I described above.
