Did you just upgrade to gcc 7.2.0? I suspect you are a victim of the so bump in libgfortran. In that case you may have to do the following emerge -1v $your_blas emerge -1v $your_lapack emerge -1v numpy and then see if scipy can be built.

It looks like your system is not set up properly. Did you eselect blas-reference and lapack-reference properly?
Well, the output is the following: hobbes ~ # eselect lapack show lib64: reference hobbes ~ # eselect blas show lib64: reference Not really sure if this is enough
If I trust the log you posted you are missing /usr/lib64/pkgconfig/cblas.pc. <slapping my face> hum, that means you also need a cblas for scipy, and that it must be properly set. So emerge -1v $your_cblas
Thanks a lot, this indeed worked. Previousy I had no cblas package, eselect cblas was reporting gsl as configured provider. Forcing the installation of sci-libs/cblas-reference did the trick. Now I need only to understand what's really happened (I was expecting some missing dep complaint from scipy), but this is another story. Many thanks again.
