Re: building emacs from tarball inside guix env

[Joshua Branson]

1) I would guess that guix environment emacs, looks in the package
definition to discover emacs' dependencies.

2) Are you trying to create a custom emacs package?
If so, then you might like my jmacs package:
https://notabug.org/jbranso/guix-packages/src/master/packages/jmacs.scm

3) I would guess "guix build <package name>".  You could have a custom
channel that is local to your machine.  Any packages in it, take
precedent over packages in guix proper.  That is to say, that your
custom emacs package named "emacs" and is available locally, would be
built instead of the "emacs" package in guix.  You could also define

I personally do this in my ~/.bash_profile

#+BEGIN_SRC sh
    export GUIX_PACKAGE_PATH=/home/joshua/prog/gnu/guix/guix-packages/
#+END_SRC
