[syslog-ng] 2.0.4 compilation issues

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:

then mv -f ".deps/cfg-grammar.Tpo" ".deps/cfg-grammar.Po"; \
else rm -f ".deps/cfg-grammar.Tpo"; exit 1; \

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

I think, therefore, I am ... not related to you.
