This is great, but if the build fails I just get an error message, there
is not output regarding where and why it failed.

--8<---------------cut here---------------start------------->8---
scheme@(guile-user)> ,run-in-store (build-package prot-common)
The following derivations will be built:
   /gnu/store/scjj4z453cwh88nlrkbxhllvkdyr90h0-prot-common-0.drv
   /gnu/store/px4b6c5sc819pjdpn53sh12p3ahyja9n-prot-common.el.drv
While executing meta-command:
ERROR:
  1. &store-protocol-error:
      message: "build of 
`/gnu/store/scjj4z453cwh88nlrkbxhllvkdyr90h0-prot-common-0.drv' failed"
      status: 1
--8<---------------cut here---------------end--------------->8---

Is there way to make it ouput the same thing as it would if I ran `guix
build` on the CLI?
