Better logging when looking for a package version in the install task
Better logging when looking for a package version in the install task

I think this used to be a wget call, so the url we were requesting to
fetch the package version would be logged by that wget call.  Since
we've changed that call to use requests and lost that logging, this adds
some of that logging back.
