Hi,

I've pushed some work on this to a dev-alternatives branch on alioth.
This is still a work in progress but I've got co-installable serial &
parallel netcdf building from this;

For the incongruity, I'd already implemented the rename when you replied
and found it easier
to simply add a symlink for compatability. I can back it out if peeople
disagree.

regards
Alastair
