Do you have lzip installed on your Internet connected machine?

As you can see from the output below, this is a host package (host-lzip). lzip 
is needed to extract some packages. Buildroot builds this host package only 
when the host has no lzip installed. The same goes for a number of other 
dependencies. See support/dependencies/. So you can either install lzip on 
your build machine, or force the download of lzip with 'make lzip-source'

Hope this helps,
