dev-libs/liblinear-210-r1 seems to be missing -lblas on its link command.

I can confirm. Same problem here.
Aha I see now, I should have looked closer. LIBS is supposed to be set in the make command via a pkg-config call in the ebuild, but this isn't working. It appears to be a quoting problem. This ebuild change seems to fix it: --- liblinear-210-r1.ebuild 2015-09-29 10:14:19.581922950 -0500 +++ liblinear-210-r1.ebuild.new 2015-09-29 10:12:15.466842332 -0500 @@ -41,7 +41,7 @@ CXXFLAGS="${CXXFLAGS} -fPIC" \ AR="$(tc-getAR) rcv" \ RANLIB="$(tc-getRANLIB)" \ - LIBS=$($(tc-getPKG_CONFIG) --libs blas) \ + LIBS="$($(tc-getPKG_CONFIG) --libs blas)" \ lib all }

hit by this, too
Since this is a pretty obvious fix, I committed it. Hope you don't mind. commit 997ff7a451b339bc2402340ab600c02c7e0cccc7 Author: Michał Górny <mgorny@gentoo.org> Date: Tue Sep 29 18:13:23 2015 +0200 dev-libs/liblinear: fix missing quoting, #561826 Add missing quoting around make parameters. Thanks to Ben Kohler for the solution. Fixes: https://bugs.gentoo.org/show_bug.cgi?id=561826 Package-Manager: portage-2.2.20
