This one is a bit convoluted. As the log shows, the exact source of the problem here is that although =sci-libs/coinor-csdp-6.1.1-r1 did have virtual/lapack in DEPEND, 'pkg-config --libs lapack' failed to retrieve the necessary information. How could it have happened? Hard to say without digging because sci-libs/lapack-reference is no longer in the tree - but my hunch is that it might have something to do with USE=eselect-ldso (seeing as app-eselect/eselect-lapack got merged shortly before lapack-reference). Perhaps lapack-reference did not call 'eselect lapack' in its pkg_postinst, resulting in a system with a complete dependency tree but no lapack.pc symlink? Anyway, a quick grep I ran a moment ago suggests that all possible providers of virtual/lapack currently in the tree do call 'eselect lapack' if need be so it's probably safe to consider the problem fixed. Hopefully I shall not be proven wrong... Oh, and for good measure the next version of coinor-csdp will error out immediately if the relevant pkg-config call fails.
