Using Racket's raco on on Guix(SD)

[Christopher Lemmer Webber]

Hello all!  Sorry for the cross-post, but I've been doing more
development in Racket lately from GuixSD... and who wouldn't want a
scheme-based distribution and a scheme language's tooling to get along
better?

Unfortunately when I try to install packages with "raco pkg install"
I get errors like the following:

   ...

I seem to remember a couple of packages failing altogether, though in
the present moment I think the result is bad performance due to not
being properly compiled, but I'm not really sure.

My reading of this is that for whatever reason, Racket is trying to
compile the files in Racket's installed directory, but that's read-only
because it's installed as part of the system (in an immutable package
collection, at that).

My guess is that the Guix package has something misconfigured so that
this compilation directory is set to the wrong place, but what?

Thanks!
