Are you following the directions in the manual?

cd /path/to/local/guix/repository/with/changes
guix environment guix

(within the environment)

./bootstrap
#unfortunately the next critical line is not in the manual
./configure --localstatedir=/var
make
./pre-inst-env guix build <package-name>

In that environment, check the value of $GUILE_LOAD_PATH.

I'm trying it, and I see it is empty. That can't be right...
