This is a timezone issue.  The “tzinfo” package cannot find the
“zoneinfo” directory in GuixSD.  If you install the “tzdata” Racket
package, things seem to settle down.  (It would be better to tell
“tzinfo” to use the system database, but that’s harder to do.)

I got better results with “raart” when “gcc-toolchain” was available
(i.e., “guix environment --ad-hoc gcc-toolchain”).  I guess it has to
compile a bit of native code, so it needs a compiler.  It still brakes
due to a syntax error, but I get the same error on Debian, so I guess
that’s something.  :)

Also, I checked all of this from Racket without grafts, and it never
complained about compiling OpenSSL stuff.  Running “raco setup” gives
some other errors, though.
