The package has migrated to rpcbind; since this hasn't been updated upstream since 2005, I'd sincerely just get rid of it if it was for me.
I don't see a valid reason for removing it from the tree. Home page is still available and it builds successfully without any QA warnings. Fixed in -r1 by setting this dependencies: DEPEND="" RDEPEND="|| ( net-nds/portmap net-nds/rpcbind )"
