Some options related to `64-bit-indices` and `complex` #6

First, thank you for your team making this tool available.

I try to install firedrake with this useful tool, and find some options that should be updated:

  1. +int64 of PETSc should be added if +64-bit-indices is turned on.
  2. +complex of PETSc should be added if +complex is turned on.
  3. For PETSc +chaco is in conflict with +int64
  4. py-pybind11 is one of the dependencies of firedrake.py-islpy.

In addition, I have a question about hypre. It seems hypre has options int64 and complex. If I want to use it in complex and int64 mode, must it be compiled in int64?

Thanks for pointing out these issues, I'm keeping track of the fixes here.

If you want to use hypre with complex problems and large problems thate require int64 indexing, you need to build PETSc with complex and int64 flags. PETSc should then ensure hypre is installed correctly, as well as ensure compatibility with the rest of PETSc.
