Did /home/dlove/.guix-profile/lib/locale contain a "2.23" directory?  If
not, then perhaps that's why the warning was emitted.

After "guix package -i guix", does the warning still show up when you
invoke "/usr/local/bin/guix"?  If so, then perhaps the reason is that
the "guix" program installed in root's profile was compiled against a
different version of glibc (2.23, I guess) than the one in your profile.

I wonder if perhaps this is the kind of problem described in "(guix)
Locales", specifically the following:
