Comment (by Bas Couwenberg):

 > I've built Proj master with Datumgrid 1.8 and it passes all the tests.

 Can you identify the commit that fixes `regress_proj`?

 > I couldn't find exactly what to do with the file once I get it, I guess
 place the contents under /nad?

 The grids from proj-datumgrid-1.8 should be unpacked in the `data`
 subdirectory of the proj source tree, as some of these grids are required
 for `make check`.

 The content of the proj-data archives, like the regional proj-datumgrid
 archive (e.g. proj-datumgrid-europe) should just be unpacked into the data
 directory after PROJ is installed as documented in
 [https://github.com/OSGeo/proj-data#proj-data README.DATA]:
 > The files in this package are in cloud-optimized GeoTIFF format and can
 be unpacked in the PROJ data directory of PROJ 7 or later. For an
 installed PROJ this may be /usr/local/share/proj or /usr/share/proj on
 unix style operating systems.

 Having the proj-data content installed locally avoids the need to fetch
 these grids from the CDN.
