Hello,
I would like to add a package to guix and send a patch but I'm facing
problems following the chapter "22.1 Building from git"

What I've done so far:

git clone https://git.savannah.gnu.org/git/guix.git


git fetch origin keyring:keyring

guix git authenticate 9edb3f66fd807b096b48283debdcddccfea34bad \

  "BBB0 2DDF 2CEA F6A8 0D1D  E643 A2A0 6DF2 A33A 54FA"


guix shell -D guix --pure


./bootstrap


./configure --localstatedir=/var --syscondir=/etc


make


After the make I have the following error.


Error: fontconfig:Didn't find expected font family. Perhaps URW Type 1
fonts need installing?


Then if I run make authenticate as stated in the documentation it
fails with the error: guix: command not found.


Have a nice day
