The substitutes is available on ci.guix.gnu.org.

And I cannot reproduce on my machine.  One example of such try:

--8<---------------cut here---------------start------------->8---
$ guix time-machine --commit=176440c056fdde6da98b11720989b1ed060ec97c \
       -- build python-matplotlib --no-grafts -d
/gnu/store/xnwy976yzkvxh2virzf2yrhr28c04075-python-matplotlib-3.5.2.drv

$ guix build 
/gnu/store/xnwy976yzkvxh2virzf2yrhr28c04075-python-matplotlib-3.5.2.drv
/gnu/store/1jv6qvrxwmh8mf6ykgs5aqrqn859b841-python-matplotlib-3.5.2
--8<---------------cut here---------------end--------------->8---

And, if --check is applied, I get:

    guix build: error: derivation 
`/gnu/store/xnwy976yzkvxh2virzf2yrhr28c04075-python-matplotlib-3.5.2.drv'
    may not be deterministic: output 
`/gnu/store/1jv6qvrxwmh8mf6ykgs5aqrqn859b841-python-matplotlib-3.5.2' differs

which means it builds fine on my machine.

Well, I do not know where the issue could come from.

Cheers,
