According to the manual:
|--load-path=directory|
Add directory *to the front* of the package module search path.
This does not work for guix environment (guix 0.16.0-3.6ddc63e):
Prepare to reproduce
$ git clone https://gnunet.org/git/gnunet.git
$ cd gnunet
guix package honors --load-path:
$ guix package --load-path=$PWD/contrib/guix -A gnunet
[...]
gnunet v0.11.0pre66-1108-g8bb29d2fb out
.../contrib/guix/gnu/packages/gnunet.scm:274:2
[...]
guix environment still installs gnunet 0.10.1 (which is defined in guix
0.16):
$ guix environment --load-path=$PWD/contrib/guix --ad-hoc gnunet
[guix]$ realpath $(which gnunet-arm)
/gnu/store/...-gnunet-0.10.1/bin/gnunet-arm
Using GUIX_PACKAGE_PATH the correct version of gnunet is installed into
the environment:
$ export GUIX_PACKAGE_PATH=$PWD/contrib/guix
$ guix environment --ad-hoc gnunet
[guix]$ realpath $(which gnunet-arm)
/gnu/store/...-gnunet-v0.11.0pre66-1108-g8bb29d2fb/bin/gnunet-arm
