Hmm. I do have 'use-package-always-ensure' set to t, but it doesn't look
like it's trying to install -- it just can't find the package.  There
should be a mechanism to tell use-package that this is a library in some
other package,

Possibly true.  I can get around this by requiring the sub-libraries in
the :config section of async.  But that doesn't quite feel right,,, :(
