It seems to me that I have gotten the checksum error from a local file corruption. My response was to go to CPAN's working directory (probably ~/.cpan) and delete file Metadata and directories build/ and sources/. After I did so the problem went away.
As for Astro::SIMBAD::Client, I am not sure of the situation about SOAP, and I am the author of that module. I know they announced the deprecation of SOAP support, but the deadline passed and it was still there. I communicated with them and they confirmed it was going away, but to the best of my knowledge it still works. Trusting my memory (a foolish thing to do) I marked all the SOAP tests TODO, added that warning, and migrated all my code that uses that interface away from SOAP.
As for XML::DoubleEncodedEntities, it may no longer be needed, though I am reluctant to drop the dependency completely for reasons that are not all technical.
Dave Cantrell is a star CPAN tester (to me anyway; of course they all are but he's one of the brighter ones). At one point he noticed test failures in Astro::SIMBAD::Client due to the fact that U. Strasbourg was, in fact, double-encoding their XML entities. His response was to publish XML::DoubleEncodedEntities and write me about it.
I can look into making XML::DoubleEncodedEntities optional, though author testing both with and without optional modules is a bit of a pain. Even if I do that it will remain strongly recommended.
