That's too bad, it's difficult to read your messages. You should
probably join us on IRC. We are on #guix on irc.freenode.net. You will
get help more quickly there.

First of all, you can't nest the `guix build` in the `guix environment`
command. You would do:
`guix environment --ad-hoc gnunet-gtk`

If gnunet-gtk has already been built, that will put it in your
environment so you can test. If not, it will build it first.

But, I don't know how to use `guix environment` with a gnunet-gtk.scm
file in any random place. I either set my GUIX_PACKAGE_PATH to point to
the correct path, or, if I am working in checkout of the Guix source
tree, I use `./pre-inst-env guix environment`, assuming that I have
bootstrapped and built the Guix from the checkout.
