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...

It is in the manual, see:

https://guix.gnu.org/manual/devel/en/guix.html#Requirements
https://guix.gnu.org/manual/devel/en/guix.html#Building-from-Git

Well, since it is a common mistake, what could be improved?

All the best,

My mistake. I keep forgetting to double-check the manual hasn't been 
changed since I last consulted it. I also forgot to change the subject, 
and swapped the to and cc headers. I guess today isn't my day...
