The reason I never cached these ones in a shared location on our server was I felt that tar balls with small hashes as filenames was too prone to collisions, especially without a package name as a prefix.  I don't know if that is a convention of iced tea, or how the fetcher handles mercurial.

That seems likely but I don’t know how to fix that.

I also don’t understand why the configure task fails after the fetch task successfully downloads the tarballs.
