python-mpi4py and check phase

[Pierre-Antoine Bouttier]

Dear all,

I try to install the « python-mpi4py » package (from the guix e18e2e4). The 
build fails during the check phase (which seems to be pretty common with 
python-packages). 

As I really need this package, I run:
$ guix install —without-tests=python-mpi4py python-mpi4py

and, as intended, it works. 

But, now, I want to install a package, which stands in our own channel, called 
python-h5py-mpi (available in this module : 
https://gricad-gitlab.univ-grenoble-alpes.fr/bouttiep/gricad_guix_packages/-/blob/master/common/python-packages.scm
 
<https://gricad-gitlab.univ-grenoble-alpes.fr/bouttiep/gricad_guix_packages/-/blob/master/common/python-packages.scm>).
 This package depends on python-mpi4py.

So, this first command fails (as intended), at the check phase of the 
python-mpi4py building : 
$ guix install python-h5py-mpi

But, more surprisingly, it fails also in the same way if I do:
$ guix install —without-tests=python-mpi4py python-h5py-mpi

When I look the mpi4py derivation that guix try to build in both case, it is 
the same. As if the —without-tests arg was not taken in account. 

Do you have an idea on whatis going on, here?

Best regards
