The netcdf libs are shipped as one tarball.

I am working with the netcdf developers on this issue actually.

This advice seems contrary to [1]. #400140 also seems to contradict [1]. Maybe
[1] needs to be updated?
For the time being, I am not adding them to the package at all.

Is there a better way than just listing Depends: libnetcdf3 in the control
file for libnetcdf-dev?
I don't think that it depends on more than the standard lib.

I have attached the new control file. Can you please check it out?
