bug#74672: Package hypre build failure for output "doc"

[Luca Cirrottola]

Hello,

I am getting failures for the package "hypre", during the building of its "doc" output. I have last tested it on 32d1dfb5545bb01c9d8d7a2465f13f2f379dd96e, and the error I get is of the form:

   error: Problems running gs. Check your installation!

(repeated many several times)

It seems to be related to doxygen, and I can reproduce it if I keep the build directory (as in https://guix.gnu.org/manual/devel/en/html_node/Debugging-Build-Failures.html) and I manually try to build the ref-manual.
That said, I have not been able to fix the problem, so I ask for help in case the original package authors have a hint.

P.S. When the package does build on certain machines, I get errors if I pass the --check option:

   guix build: error: derivation `/gnu/store/1i8b07ll0m5j2p2m7z0wcxqgp407b5qc-hypre-2.20.0.drv' may not be deterministic: output `/gnu/store/g8ci2qjbz49aq2zwn8hbl3dl44d30rfg-hypre-2.20.0-doc' differs

Thanks,
Luca
