I know this patch has caused a bit of confusion as it blew up in testing. 
I can't explain why you didn't see that but I did spot why its breaking. 
I've cut this email to the bare bones of the problem for clarity.

In util-linux-uuid, you set PACKAGES as above with util-linux-libuuid.

In util-linux, you set it to refer to a util-linux-uuid package which 
does not exist. It needs s/uuid/libuuid/. RDEPENDS refer to PACKAGES 
namespace so need to be consistent.

Why the tools haven't been clearer about the issue, I don't know but
that is no doubt causing many of the issues.

Cheers,

Richard
