Dear Wien2k community!
I've compiled Wien2k_10.1 with ACML and gfortran with self compiled fftw2 and scalapack. Now we have segfaults running kgen and tetra.
Here is some info:
kgen

Could you please push me on where to look?

P.S. I don't want to install ifort and mkl, because it costs much for academics (and personal licenses don't suit).
