You can see this in the proj list thread: http://lists.maptools.org/pipermail/proj/2015-September/007209.html\r\nand an issue from May last year: https://github.com/OSGeo/proj.4/issues/274\r\n\r\nThe resolutions are either to add the missing file to the share/proj folder from:\r\nhttps://github.com/OSGeo/proj.4/blob/master/nad/proj_def.dat\r\nor update your PROJ to 4.9.2 (or a patched 4.9.1 - I seem to recall Fedora/RHEL packagers responding to the cited thread. It was Howard who committed the required fixes in Proj, but he is so busy that it slipped his mind. Bottom line, 4.9.0 and 4.9.1 as released (unpatched) are critically broken when users do not explicitly declare +ellps= (or equivalents). 4.9.2 is fine. The message is to alert the user to the need to fix their PROJ4. Users of Windows and OSX CRAN binaries of rgdal are protected already because Proj is statically linked and the missing file added to share/proj, but if you install rgdal from source and provide your platform PROJ, rgdal will try to protect you from known issues in your installation. Googling for proj_defs.dat would have told you all of the above.\r\n"}}
