There is no configure patch for irssi-0.8.9 in the current Portage tree and here is how src_unpack ends: * Cannot find $EPATCH_SOURCE! Value for $EPATCH_SOURCE is: * * /usr/portage/net-irc/irssi/files/irssi-0.8.9-configure.patch I'd say that no patch is necessary for this version of irssi. The epatch line can IMO be safely removed from the ebuild.
How can you tell that no patch is necessary?
i agree with you. the patch isn't necessary because the patch of version 0.8.8 just changed a 'head -1' to a 'head -n 1', but the configure of 0.8.9 already uses the -n parameter
removed epatch line, no patch required for configure anymore. As mentioned in the comments they are now using head -n.
