oops, sorry, it's a wrong guess, I suppose.
What is the branch you are installing? master from github, which is Sage 9.2 ?
Or the development branch, 9.3.beta7?
Was it an attempt to re-build after git pull,or a fresh install?
Fresh install should work, but for an update, you might need a serious clean-up:
make bootstrap-clean distclean
Sage has a bit fragile system of re-creating missing .pc files for
(c)blas/lapack, and
recent changes in the build system might have confused it (so that's
why a fresh rebuild
might be needed)
