[Debian-med-packaging] Bug#936609: cblas / gsl hint needed (Was: Bug#936609: Ported ghmm to Python3 but issues with clapack)

[Andreas Tille]

Hi again,

with my last mail I wanted to express:  Hmmmm, to stupid to turn
this hint into real code.  Any more detailed hint / patch would be
really welcome.

Kind regards

      Andreas.
