sa-exim-3 not working

Hi All.

I have installed Exim 4.14. it has been built and is working.

I then installed SpamAssassin 2.54 via CPAN.
All compiled 100%

I then built sa-exim-3.0 and applied the patch.

Now nothing is working.

When I add the line
#local_scan_path = /usr/exim/local_scan/accept.so
   local_scan_path = /usr/exim/local_scan/sa-exim-3.0.so

i get the following error:

Starting exim: 2003-05-14 14:35:35 Exim configuration error in line 141:
  main option "local_scan_path" unknown
                                                           [FAILED]

Any pointers in the right direction would be appreciated.
