Hello,

Had an issue with compiling 1.1.0 from source on
linux (64-bit slackware, almost current) with
guile 3.0.4.

First thing, it couldn't find guild with the
default configure template. I had to add a
kludge (configure.ac.diff, attached).

Then, it wouldn't compile some files in guix/
subdir. The diagnostics went like this in each case:

WARNING: (guix swh): `define-json-mapping'
imported from both (guix json) and (json)
WARNING: (guix swh): `define-json-mapping'
imported from both (guix json) and (json)
ice-9/eval.scm:293:34: error:
define-json-mapping: unbound variable
hint: Did you forget `(use-modules (json record))'?

I took the compiler's suggestion and added
'(use-modules (json record))'. Have no idea how
that works.
I'm attaching the patch for that
compilation_define-json-mapping.diff.

Hope that helps.
