So I start to understand. lz4 depends on valgrind. I do not know why.
It is given as a native input, so probably the tests require valgrind?
If yes, that looks a bit excessive to me - the developers of lz4 are very
welcome to check for memory leaks from time to time, but doing this at
every compilation is excessive. What do you think of dropping the valgrind
input (at the same time as updating valgrind, say)? It does not seem to be
necessary, as it is already dropped on architectures that do not provide it,
without further ado. Maybe this is what hides it from "guix refresh" and
"guix graph"?

Then texlive-ms depends on lz4 and indirectly on valgrind:
$ ./pre-inst-env guix build --system=powerpc64le-linux texlive-ms -n
  /gnu/store/j0wzdc36vvgvj4zh49a71sc115m6m76b-texlive-ms-59745.drv
  /gnu/store/jl6p6m1zngi1rjl2808zvnb9wpiphhjf-texlive-ms-59745-checkout.drv
  /gnu/store/gfkdb5pys2b8dr2mqgs5gbwfflwlc4kh-subversion-1.14.2.drv
  /gnu/store/xw5kdli3i92iwd7wpplcb0p89g1p3a29-lz4-1.9.3.drv
  /gnu/store/z6kf2pg48b9a87angabkfyfv4knhhwjy-valgrind-3.17.0.drv

More precisely: texlive-ms is downloaded via subversion via
simple-texlive-package in (gnu packages texlive), which relies on
texlive-origin from (guix build-system texlive).

$ ./pre-inst-env guix build --system=powerpc64le-linux subversion -n
The following derivations would be built:
  /gnu/store/gfkdb5pys2b8dr2mqgs5gbwfflwlc4kh-subversion-1.14.2.drv
  /gnu/store/xw5kdli3i92iwd7wpplcb0p89g1p3a29-lz4-1.9.3.drv
  /gnu/store/z6kf2pg48b9a87angabkfyfv4knhhwjy-valgrind-3.17.0.drv

So subversion depends on valgrind! And all new simplex-texlive-packages
are concerned.

I think the solution is to indeed remove valgrind from the native inputs
of lz4.

And I think there is a shortcoming in "guix refresh" that it does not
take the source code of packages into account.

What do you think?

Andreas
