There's your problem. The only way to reliably compile, especially
something where an old version might already be loaded, is to use a
fresh Emacs instance. There's no reason the "package manager" could not
spawn a separate Emacs in batch-mode as a sub-job to do the compilation.

cc-mode tries to have some voodoo to get around this, but please, please
don't go down that road.

I guess nobody ever expected the package manager to be used to load a
different version of something that was already in Emacs.
