However, input labels don=E2= =80=99t have a role here since =E2=80=98--with-input=E2=80=99 matches packages by name. So most likely, we=E2=80=99d (1) use OpenBLAS by default everywhere instead= of netlib blas/lapack, and (2) you=E2=80=99d use: --with-input=3Dopenblas=3Dopenblas-tuned WDYT? Ludo=E2=80=99.
