[Exim] Build problem

Hi,

I've managed to get exim to compile with MySQl support (thanks Suresh)
without any errors and get the message:

>>> exim binary built

but when I "make install" I get the following:

macmillan: {/etc/exim-3.34} [ROOT] # make install

Installation directory is /usr/sbin


*** /etc/exim-3.34/build-Linux-i386/exim does not exist or is empty
*** Have you built Exim successfully?
*** Exim installation failed ***
make: *** [install] Error 1

How can I get a message that the binary was built, and then it not be there?
I've done a 'whereis', and I get the existing binaries, exim and exim.0 in
the /usr/sbin directory, but no other binaries anywhere.

Any clues gratefully received.

Dan
