That must be my mistake yes; the output of 'guix build --check --no-grafts
python-deeptools':

--8<---------------cut here---------------start------------->8---
guix build: error: derivation `/gnu/store/hky07zjsvai0x3n99lqmgyh6rhld6v4s-deeptools-3.1.3.drv' may not be deterministic: output `/gnu/store/0j8200f20mp5grjkjh5kw2q9a67gw3rn-deeptools-3.1.3' differs
--8<---------------cut here---------------end--------------->8---

left me confused about what and what store items were
being compared exactly, and I must have went on and diff'd something not quite
right, sorry! Perhaps the store output differing should be mentioned
explicitly in the error?

The suggested command doesn't help :-(, as the ...-check output
doesn't seem to exist:

--8<---------------cut here---------------start------------->8---
$ guix build --check -K deeptools
The following graft will be made:
