If I'm going to rebuild a good package I might as well use the latest
version of dhcpcd, so I'll start with 5.6.7.

I am not sure if
http://roy.marples.name/downloads/dhcpcd/dhcpcd-5.6.7.tar.bz2
uses cmake or automake.  The tarball contains a Makefile, and their
configure script has the comment, "Try and be like autotools configure,
but without autotools", so I assume it is just using gnu make.  It does
contain a Makefile... but I don't see how to use it from:
http://buildroot.org/downloads/manual/manual.html#generic-package-tutorial

So I tried to make a pacakge using 
$(eval $(generic-package))

When I run make in buildroot, the package is not downloaded, or built.
Below is my package file so far.
