Hi folks,

I'm working on adding MediaGoblin to Guix and we're actually getting
fairly close! I'm having some trouble packaging python-soundfile and
would love some help (patch attached).

When I run:

  ./pre-inst-env guix build python-soundfile

I get:

  OSError: cannot load library 'libsndfile.so.1': libsndfile.so.1:
  cannot open shared object file: No such file or directory

The libsndfile package is included as an input, but I guess there's
something I'm missing.

Regards,
Ben
