Compile problem (Solaris)

Hi,

I've been running Exim for 6 months or more for about a dozen domains, and
it's been much less hassle than Sendmail.
I'm trying to add SpamAssassin to it, but am having a problem with it,
wonder if anyone can help?

I can build and install the binary, then when I try to start Exim, I get
the message:
2004-01-29 20:45:02 Exim configuration error in line 576 of
/usr/exim/configure:  local_scan() options not supported:
(LOCAL_SCAN_HAS_OPTIONS not defined in Local/Makefile)
lines 575-7 of /usr/exim/configure are:
begin local_scan
local_scan_path=/usr/exim/local_scan/sa-exim-3.1.so

as suggested by the SA-Exim instructions.
Defining LOCAL_SCAN_HAS_OPTIONS in Local/Makefile means I can't even build
Exim (get the same message as
http://lists.merlins.org/archives/sa-exim/2003-August/000560.html -
undefined reference to 'local_scan_options')

Versions of stuff:
Exim 4.30
Sa-Exim 3.1
Gcc 2.95.3 20010315 (from www.sunfreeware.com)
GNU make 3.78.1 (also from www.sunfreeware.com)
SPARC Solaris 8 02/02

I seem to be stuck in a loop - I can't compile it with
LOCAL_SCAN_HAS_OPTIONS, and can't run it unless it was compiled with it!

Any help greatly appreciated,

Steve.
