I think you also need to set the ‘GIT_SSL_CAINFO’ environment variable.
For instance:

     $ guix package -i nss-certs
     $ export SSL_CERT_DIR="$HOME/.guix-profile/etc/ssl/certs"
     $ export SSL_CERT_FILE="$HOME/.guix-profile/etc/ssl/certs/ca-certificates.crt"
     $ export GIT_SSL_CAINFO="$SSL_CERT_FILE"

Can you confirm?

Thanks,
Ludo’.
