The homepage for xmms-lirc is wrong (it is currently set to http://www.xmms.org/plugins_search.html?mode=search&query=lirc). I'm not able to find the correct url, perhaps it is now migrated to ctrlxmms?
It moved to http://xmms.org/comments.php?show=P36 or www.lirc.org. I fixed the ebuild with the first link.
