[Proj] New Zealand grid?

[William K]

I just noticed the new datum grid files (v1.3) that add the New  
Zealand grid.  I put these in the proj_src/nad folder, reconfigure,  
make and install, but I don't see any indication that the New Zealand  
grid file has been incorporated into proj - nothing installed in  
share/proj, and I can't tell if it's added to the library in some way.

Is this a lark?  Or did I miss something to install this file  
(nzgd2kgrid0005.gsb)?
