No, I get:

guix build: error: /home/vince/guix-packages/linux-libre.scm:8:2:
package `linux-libre-for-myself-4.5' has an invalid input: ("kconfig"
#<<local-file> file: "./my-kernel.conf" absolute: #<promise
#<procedure 55079f0 at ice-9/eval.scm:416:20 ()>> name:
"my-kernel.conf" recursive?: #f>)

Which is very similar to what I was getting yesterday evening, with the various
modifications that efraim asked me to try on IRC
