I think a store item doesn't know where it comes from, so you can only find its 
runtime references. If you have a package foo, you can find its build-time 
dependencies with guix graph:

guix graph foo

There's even a script that was shared here to show the path between two nodes 
of a guix graph, but I can't find it anymore.
