Warning message: Will it create a faulty build

Below are the two warnings I get .

WARNING: Makefile 'package/feeds/telephony/asterisk-16.x/Makefile' has a dependency on 'liblua5.3', which does not exist
WARNING: Makefile 'package/feeds/packages/openvswitch/Makefile' has a dependency on 'kmod-nsh', which does not exist

While building e0e9fd4bddee7df5e1b1b284fb4ffd9c589c776e for WR841V14 and WR841V13 I get above warnings but no build errors or build fails. Should I safely Ignore them?

Edit: Thanks tmomas for the edit.
