Partially answering my own question, by rifling through the files listed
in the `guix build ...` output I can eventually find a file of the form
/gnu/store/...-NAME-builder
which contains the S-expression created from my G-expression, and which
showed me that the generated program was not valid (it was trying to
use a string as a function.
Cheers,
