How did you build them? If you had them built, you could add this line to
the __init__() function in config/PETSc/packages/SCALAPACK.py and
config/PETSc/packages/blacs.py

    self.worksonWindows   = 1


If you want to try --download-{scalapack,blacs}, you can also add this line

    self.downloadonWindows= 1


Let us know if it works, I assumed it was disabled because it didn't.

You can't, those are hard dependencies. You could use SuperLU_DIST which
works with --download-superlu_dist.
