Thanks for the explanation. I was confusing scheme variable names and package names, which are the same most of the time. With (define-public libjpeg-8 (package (inherit libjpeg) (name "libjpeg") (version "8d") $ guix-package -i libjpeg-8d indeed works as expected. However, now $ guix-build libjpeg-8d returns libjpeg-8d: unknown package Using the scheme variable name does not help: $ guix-build libjpeg-8 libjpeg-8: unknown package Could the behaviour of guix-build be made the same as that of guix-package?
