Ok, i see now.  Your diagnosis is correct: I missed a name change and
we fixed this in 0.8.5.

I'm going to put out another release that addresses as many of Tyce's
concerns as possible plus builds a real libpnetcdf with fortran
bindings.

You are definitly the first to try out our fortran side of things.  We
have tested the C side pretty well, but haven't spent as much time
hitting the fortran side of things.   Thanks for helping us out on
that front.

We all have different levels of risk tolerace.  However, I know
Jianwei, Rob, the rest of the parallel-netcdf guys and I will address
any problems you encounter and do what we can to make sure this
software helps you do your science.   Thanks for bearing with us.   We
are using the same fortran bining procedure that the MPICH-2 project
is using, so we are pretty confident that it works: we just need to
figure out the quirks of various platforms.

We really do appreciate your help as an early user.  Thanks.
