ncarg: reinplace didn't change anything

[ryandesign (Ryan Carsten Schmidt)]

Using the patch from #15514 we see that ncarg runs various reinplaces that don't actually do anything:

$ sudo port install

The reinplaces should be either adjusted so that they do something, or removed (as appropriate).

Committed in r96193. The warning of reinplace is a good idea. I will upload the updated patch.
