RAR version 3.9.0 has been out for a while. I took the opportunity to fix the ebuild a bit: a *.diz file is no longer included in RAR, and QA_DT_HASH is used to suppress LDFLAGS warnings (they don't make sense on binary-only packages.) Also, I noticed that the RAR license has changed and differs from /usr/portage/licenses/RAR. I am attaching the ebuild patch as well as the new license (I'm not attaching a patch for the license since it's bigger than the license itself.)
