I had suggested that the beta be used as an interim solution until the released version is available in a few weeks.
Solving the issue of building ScaLAPACK is a more difficult issue and I don't have a lot of suggestions there. However, I will request that the developer who builds ScaLAPACK for MKL look at your issue and respond in this forum.
Sorry I can not be of more help. Perhaps other developers who visit the forum can offer suggestions.
