Well, the .gem files are not binaries, they are tar simply files and also contain files with some metadata.
When you call the "gem install --local foo %{SOURCE0}", it takes the .gem file, untars it and produces some necessary files (like .gemspec file) from the metadata.
This is the reason why we feel that rebuilding is not necessary. It doesn't make sense to untar the source, then tar it and finally untar it again (without actually doing something with it) and use the "gem install" command anyway, as now written in [1]. The output is _exactly_ the same as in our proposal, but you need twice the steps to do it.
