Thank you André.  Unfortunately, Guix prefers stable packages and if
there is no urgent need for a specific intermediary version, it's often
best to simply wait for the next stable release.

In the case of SBCL, a new stable version is release at the end of each
month.  The easiest fix (and probably the right thing to do) is to
simply wait some 20 days :)
