You can download a little pre-made neoircd configureation for neoircd here, http://neoircd.org/configs/atheme.conf
first just lets install some packages.
RHEL:
yum install gcc gcc-g++ git
DEBIAN/UBUNTU:
apt-get install gcc g++ git
ARCH:
pacman -S gcc g++ git
So next, lets download atheme via git (As it provides on the website you can use wget but git is a little easier).
git clone git://git.atheme.org/release/atheme-6.0.git (STABLE)
Now, lets compile it:
cd atheme*
./configure;make;make install
Then, we'll go to the new atheme dir ~/atheme so,
cd ~/atheme/etc
cp -rf atheme.conf.example atheme.conf
nano atheme.conf
You May Copy our atheme config from the first line too.
So, edit the config until you feel like you're Done.
Now Run Atheme via ~/atheme/bin/atheme-services
So Just Setup the link blocks and you should be done.
You Should see all the Services join the logchan (default in our config: #Logging)
Once this is all done, you can go ahead and use your Services.
Thanks,
