Are you sure you were running ~/.guix-profile/bin/sbcl?

I’ve just tried this on GuixSD, to check whether sbcl systematically
looks for things in /usr:

--8<---------------cut here---------------start------------->8---
$ strace -f -o ,,s $(guix build sbcl | head -1)/bin/sbcl 
This is SBCL 1.2.8, an implementation of ANSI Common Lisp.
More information about SBCL is available at <http://www.sbcl.org/>.

$ grep /usr ,,s
[ nothing ]
--8<---------------cut here---------------end--------------->8---

However, it loads /etc/sbclrc.  Could it be that your host distro
provides such a file, which tweaks sbcl into reading from /usr/lib64?

Thanks for the report,
Ludo’.
