Packing problem for instantmusic

[Stefan Reichör]

Hi there,

I am currently trying to package instantmusic.

There are several things that I have already solved:

- The official release is very old - so I use the latest git revision
- I listed the dependencies as propagated-inputs
- The build must be started in the directory instantmusic-0.1

Here is what I have got so far:

(define-public instantmusic
  (let ((commit "300891d09c703525215fa5a116b9294af1c923c8")
        (revision "1"))
    (package
      (name "instantmusic")
      (version (string-append "0.1-" revision "." (string-take commit 9)))
      (source (origin
                (method git-fetch)
                (uri (git-reference
                      (url 
"https://github.com/yask123/Instant-Music-Downloader.git";)
                      (commit commit)))
                (file-name (string-append name "-" version "-checkout"))
                (sha256
                 (base32
                  "0j7qivaa04bpdz3anmgci5833dgiyfqqwq9fdrpl9m68b34gl773"))))
    (build-system python-build-system)
    (propagated-inputs
     `(("python-requests" ,python-requests)
       ("eyed3", eyed3)
       ("python-beautifulsoup4" ,python-beautifulsoup4)
       ("youtube-dl" ,youtube-dl)))
    (arguments
     '(#:phases (modify-phases %standard-phases
                  (add-before 'build 'change-directory
                    (lambda _
                      (chdir "instantmusic-0.1")
                      #t)))))
    (home-page "http://iyask.me/Instant-Music-Downloader/";)
    (synopsis "Command line app to download a song from youtube")
    (description "Download a song from youtube in .mp3 format.")
    (license license:expat))))

Here are the last lines from the guix build output:

I sadly have no idea hwy the egg_info task is not able to access 
instantmusic.egg-info/top_level.txt

I looked in other package descriptions for egg_info. But I found nothing useful.

Does someone have a clue how to debug/fix such build problems?

Thanks,
  Stefan.
