Hi,
This patch fixes the error that prevents SuperCollider from starting. On
Guix 229f4fa9522fb56b014ee9c0d8111e8fb6da764d and after having followed
instructions from [0], the behavior is the following:

The implemented solution is to hardcode SCClassLibrary's path into
SuperCollider.

Subject: [PATCH] gnu: supercollider: Enable SCClassLibrary library lookup.

This hardcodes the path of SCClassLibrary to fix a lookup error that was
preventing SCServer's boot.

* gnu/packages/audio.scm (supercollider): [source]: Fetch via git.
[configure-flags]: Build Release target.
[phases]: ...hardcode path using substitute* in a new phase.
