Cannot install package / NAMESPACE file required

[MatthiasHinz]

Hi,
i am not able to install rgdal2 according to the Readme.md. The installation fails with the error

ERROR: a 'NAMESPACE' file is required

Also, there seems to be a problem with roxygen2:

First time using roxygen2. Upgrading automatically...
Updating roxygen version in /tmp/RtmpmOP7q5/devtools4de8213c4e7d/thk686-rgdal2-451b53c/DESCRIPTION
Loading required package: 
Failed with error:  'invalid package name'

The full sequence of commands and messages are attached below. I got similar results also when I tried the same with the Docker image rocker/geospatial.

Can you please help? Thanks.

Something has changed in roxygen2 that broke it.
With an older version of roxygen2 (v. 5.0.1) the install was succesful for me.
