Trouble with AIX & Exim 4.30 & sa-exim

Hello All,
    I'm some difficulties getting sa-exim to compile and run with Exim 
4.30.   First problem is:  I haven't been able to get the, " 
localscan_dlopen_exim_4.20_or_better.patch " to work correctly.  It 
always returns, " I cannot find a patch in there anywhere".   Any ideas?  
    Also, when I run make, I get the following errors:
Building sa-exim-3.1.so

-DSPAMASSASSIN_CONF=\"/app/exim/sa-exim.conf\"

Does this have something to do with Exim not being patched with the 
above file?   Thanks in advance for any light you guys can shed on the 
subject. 
Sincerely,
