OK, I uploaded mpqc_2.3.1-10 now, it should be synced to Ubuntu.

I tried to build libghemical/ghemical against it, but it turned out that
libghemical is not binNMU-safe (see #649382); manually increasing the
version number and then building ghemical against that made the build
succeed, though.

Daniel, are you going to update libghemical/ghemical to 3.0?  I probably
won't have more time to spend on this right now, but could look into it
at some point if you are busy as well.


Cheers,

Michael
