The recipe for reproducing the wordlist tarball in the hunspell-en specfile doesn't result in the same tarball that's in lookaside cache. It's not a matter of anything changing in upstream svn since it was created, the contents just differ quite a bit. The recipe and/or the tarball should be updated, and it should use svn export instead of checkout to avoid .svn dirs, and use xz instead of bzip2 to save some more space.
