The xmds2 package is an Arch:all package. It does not compile binary 
programs or libraries at build time that are be linked against BLAS. It 
needs an optimized BLAS library for running the unit tests, whose code in 
C++ is automatically generated and compiled on the fly.


I will release a new version of the package that build-depends and 
depends on libopenblas-dev | libblis-dev.


I am wondering whether we should propose my patch [*] (or something 
similar) to the upstream authors. Thoughts are welcome.

Sure, I know and approve of the email BTS, but it doesn't help for
contributing.  I'm happy to have a salsa account, as I did alioth(?),
just not to interact with Google and be put into semi-impossible captcha
hell.
