MacOS X tiger compile files w/ 'SIOCADDRT' undeclared

[Peter Burkholder]

I've been trying to compile cfengine both from  fink (v. 2.1.11) and  
from source download (v 2.1.15).  In either case the build process  
fails with (v. 2.1.15 in this example):

if gcc -DHAVE_CONFIG_H -I. -I. -I. -I/sw/include/db4 -I/sw/include  - 
I/usr/include -I/sw/include -g -O2 -Wreturn-type -Wmissing-prototypes  
-Wuninitialized  -g -O2 -I/sw/include/db4   -g -O2 -I/sw/include/db4 - 
MT ifconf.o -MD -MP -MF ".deps/ifconf.Tpo" -c -o ifconf.o ifconf.c; \
then mv -f ".deps/ifconf.Tpo" ".deps/ifconf.Po"; else rm -f ".deps/ 
ifconf.Tpo"; exit 1; fi
ifconf.c: In function 'SetDefaultRoute':
ifconf.c:489: error: 'SIOCADDRT' undeclared (first use in this function)
ifconf.c:489: error: (Each undeclared identifier is reported only once
ifconf.c:489: error: for each function it appears in.)
make[2]: *** [ifconf.o] Error 1
make[1]: *** [all] Error 2
make: *** [all-recursive] Error 1

In googling about I do see that DHCPD does have some notes about a  
"broadcast route portability bug" but I don't see how I can apply  
that to this case (ref. http://www.net.princeton.edu/software/dhcpd/ 
INSTALL.txt)

Can anyone provide some help, please?

Thanks,

Peter
