The error message is wonderfully obscure, but the actual problem is here:

%doc wipes out anything else in the doc directory, in this case AUTHORS 
and probably something else too, so when rpm tries to put the files into 
the cpio archive it fails because the files don't exist. You need to use 
either %doc or manual directory ownership of the doc directory, you can't 
mix them.

And of course the whole thing is just stupid behavior from rpm, the only 
excuse for this is "it's always been like that"...
