Great.

I believe as general rule, flags such as -known-64-bit-xxx are only
required to be specified by the user when using system provided packages
(actually any package not installed by petsc' configure). If you use
--download-yyy then petscs' configure defines how package yyy is to be
configured and built, hence it knows whether it used 64 bit ints, or not -
the user does not (and probably should not) provide a flag to indicate what
petsc configuration already knows


Thanks,
  Dave

I will try again later with the latest version.
