Why are we adding '-guix1' as a version suffix?

If possible I'd prefer to not pull in ruby-asciidoctor, it pulls in
pandoc, which will limit this package to GHC supported systems only, ie
x86_64 and i686.

You'll also need to import pretty-print at the top of the file.

this can be (list (string-append "/lib/emilua-"
            (version-major+minor version)))
