Dear maintainer:

During a rebuild of all packages in unstable, this package failed to build.

Below you will find the last part of the build log (probably the most
relevant part, but not necessarily). If required, the full build log
is available here:

https://people.debian.org/~sanvila/build-logs/202610/

About the archive rebuild: The build was made on virtual machines from AWS,
using sbuild and a reduced chroot with only build-essential packages.

If you cannot reproduce the bug please contact me privately, as I
am willing to provide ssh access to a virtual machine where the bug is
fully reproducible.

If this is really a bug in one of the build-depends, please use
reassign and add an affects on src:scotch, so that this is still
visible in the BTS web page for this package.

Thanks.

The error "Deprecated variable: schizo_proxy" is Bug#1148924,
outside scotch's control.

The error "Deprecated variable: rmaps_default_mapping_policy" can be
easily fixed in debian/rules. PRTE_MCA_rmaps_default_mapping_policy is
to be updated to PRTE_MCA_mapby

But then the error "mapping request contains an unrecognized qualifier"
I do not understand. The same variable PRTE_MCA_rmaps_default_mapping_policy
(or PRTE_MCA_mapby) is used in other packages with no
such problem. ":oversubscribe" is the correct syntax,
c.f. https://github.com/open-mpi/ompi/issues/8955#issuecomment-846272943

Running the test manually passes fine without this
"unrecognized qualifier" error.

I have no idea what to do with this error,
unless OMPI_MCA_rmaps_base_oversubscribe=true works as an alternative
