I use the R packages rgdal and rgeos extensively (currently with R v3.2.2). Recently, on my ubuntu machine (ubuntu v15.10), when I load the rgdal package, I see the following:
> library(rgdal)
Loading required package: sp
rgdal: version: 1.0-7, (SVN revision 559)
Geospatial Data Abstraction Library extensions to R successfully loaded
Loaded GDAL runtime: GDAL 1.11.1, released 2014/09/24
Path to GDAL shared files: /usr/local/share/gdal

WARNING: no proj_defs.dat in PROJ.4 shared files

I have seen on a recent r-sig-geo posting that this is a known issue, and that an update to the rgdal package has been released to fix this issue. However, despite reinstalling the rgdal package, reinstalling gdal and proj4 with the following:
sudo apt-get update && sudo apt-get install libgdal-dev libproj-dev
I see no difference. This problem generates hundreds of warning messages when I use the functions of these packages.
In comparison, on my mac, if I load the rgdal package, I see
> library(rgdal)
Loading required package: sp
rgdal: version: 1.0-7, (SVN revision 559)
Geospatial Data Abstraction Library extensions to R successfully loaded
Loaded GDAL runtime: GDAL 1.11.3, released 2015/09/16

So there are clearly updates to gdal and proj.4 that are not making it onto my linux machine.
Does anybody have any ideas how I can get the updates?
Thanks!
I ended up compiling both proj4 and gdal from source, by cloning the respective github repositories.
