You could hardwire a relative reference to it though.

I don't know if I want to encourage this kind of repackaging. There
are various downsides (such as possible deployment of two differently
repackaged versions of the same code) and I think some of the burden
should be placed on the repackager. After all, after repackaging, the
repackager is really responsible for the repackaged code.
The nice thing about absolute imports is that it's very simple to
write a tool that changes all absolute imports of a given package into
some other import, if you really want that.
