[petsc-dev] why does the Ubuntu PETSc package install coarray Fortran?

[Jeff Hammond]

I understand a lot of these but how does PETSc depend on OpenCoarrays?

Obviously, I do not fault the PETSc developers for this, because I know
they are not using coarray Fortran, but maybe somebody on this list knows
who is creating the Ubuntu packages for PETSc.

If there is a simple way to understand this using Apt, please share.  I ran
apt-rdepend but do not see any reference to the coarrays stuff, so I don't
know how it is getting included here.
