Please add a comment as to why recursive? is needed; typically, that's
to pull bundled sources that should be pruned as much as possible,
e.g. at least those being used from the system should be removed in the
origin snippet below.  I've used a local 'delete-all-but' definition in
the past, for example in the turbovnc package, that may be useful here.

You don't ever need to import the (guile) module; it's always loaded
(except pehaps in pure R7RS mode, but that's not used in Guix) :-).

I'd research a bit more and write ';no test suite', if that's truly the
case.  The test target is sometimes named differently.

I'd write a full fledge comment briefly mentioning what's the error we
get otherwise, with a (see: $url) reference at the end.  Use complete
(including punctuation) sentences for line comments.  Margin comments
can be incomplete and unpunctuate sentences.

With the above addressed, it LGTM.  Could you please send a new revision?
