First of, supposing you are on amd64, does
/usr/lib64/pkgconfig/lapack.pc
exist? It should be a link pointing to
../../../etc/env.d/alternatives/lapack/_current/usr/lib64/pkgconfig/lapack.pc
itself a link to /usr/lib64/pkgconfig/reflapack.pc
It is possible that some of these links have not been created properly.
There used to be bug about it on prefix (I don't know if anyone improved
my prefix bandaid). There is also the possibility that remnant from the
non-sci overlay mechanism interfere.
