In the webalizer ebuild the line dodoc README* CHANGES Copyright sample.conf ${FILESDIR}/${PV}/apache.webalizer should be changed to dodoc *README* CHANGES Copyright sample.conf ${FILESDIR}/${PV}/apache.webalizer so DNS.README gets installed too.
this is a fairly trivial thing, so i'm not going to bump the revision number and force everyone to recompile, but its fixed in cvs (on the rsync servers in a few hours) and you're welcome to reemerge -r12 to get the docs.
