So
../../../etc/env.d/alternatives/lapack/_current/usr/lib64/pkgconfig/lapack.pc
is not a symlink to /usr/lib64/pkgconfig/reflapack.pc?
That should be provided by lapack-reference using the alternative2
eclass. /usr/lib64/pkgconfig/lapack.pc is created by eselect.

yes, you may have to delete some left over files and re-emerge
lapack-reference.
