Do you have the SBCL_HOME environment variable set while running SBCL?
If so, make sure it's correct, or simply unset it. (It *should* work
when it's unset.)
I can't reproduce the issue using SBCL 1.2.8 from Hydra, i.e.:
/gnu/store/2vlqnaj650nr4hv5iq19xf402vc2l60l-sbcl-1.2.8/
I don't have SBCL_HOME set, have no /etc/sbclrc, and have no other
installation of SBCL on my system; when I run .../bin/sbcl from the
above package, it fires up the REPL just fine. I can also install it
into my profile and run ~/.guix-profile/bin/sbcl.
I also reproduced Ludo's test and similarly had no output from grep.
For the record, someone had raised a similar issue before, and it came
out they had SBCL_HOME set to a wrong value:
https://gnunet.org/bot/log/guix/2015-11-19#T820295
So either it's that, or something else unusual might be going on in your
system...
To make absolutely sure SBCL_HOME is unset before starting up SBCL, you
can run the command "unset SBCL_HOME" in your shell, and run "sbcl" in
the same shell session right after that.
Hope that helps!
