This is the situation alternatives(8) was designed for - to mediate names and functions. If a package is dependent on one or the other, its location in /var/lib/pkg/ should be wired in. My PATH seems to include /usr/lib/lapack, appended by /etc/profile.d/lapack0.sh. Perhaps openblas could provide the same for its clients? -- Take care.
