[syslog-ng] 2.0.4 compilation issues

[Douglas J Hunley]

I'm trying to compile 2.0.4 using:
./configure --prefix=/usr --sysconfdir=/etc --enable-dynamic-linking

and right away, it fails telling me that libnet-config isn't found. Which is 
correct, I don't have it installed. There wasn't anything in the tarball that 
told me I needed to. A 'grep -ri libnet *' shows a bunch of check in the 
configure and this ChangeLog entry:
ChangeLog:      * configure.in: added --with-libnet and --enable-spoof-source

Is there a reason this dependency isn't documented inside the tarball, or am I 
missing some file/reference somewhere?

Moving on, I went and downloaded the latest libnet, only to find out that the 
latest doesn't include libnet-config (it's deprecated). So now I have to 
downgrade my libnet.

Moving on again, the compile fails:
if 
gcc -DHAVE_CONFIG_H -I. -I. -I..   -I/usr/include/glib-2.0 -I/usr/lib/glib-2.0/include   -I/usr/include/eventlog   -D_BSD_SOURCE -D__BSD_SOURCE -D__FAVOR_BSD -DHAVE_NET_ETHERNET_H -DLIBNET_LIL_ENDIAN -D_GNU_SOURCE -D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64  -O3 -march=k8 -mmmx -msse -msse2 -m3dnow -pipe -fomit-frame-pointer -Wall -g -MT

  -c -o cfg-grammar.o `test -f 'cfg-grammar.c' || echo './'`cfg-grammar.c; \
then mv -f ".deps/cfg-grammar.Tpo" ".deps/cfg-grammar.Po"; \
else rm -f ".deps/cfg-grammar.Tpo"; exit 1; \
fi

And there I'm stuck. 

On a whim, I 'upgrade' my libnet and it suddenly compiles w/o issue..

I think the libnet dependency needs to be re-examined
