We tried to install R-devel (2015-11-12 r69623) and R-3.2.2 on our CentOS 6.5 server. This gave an error because of libcurl 7.28.0 or later is required.
Now to not screw with the hosting system we installed curl within the installation folder and gave the library as a flag to the configure script.
The configure does not complain, but the make script stops with the error:
libcurl.c:40:3: error: #error libcurl 7.28.0 or later is required.
We found two ways to solve this:
1. the ugly one is just to run make again, which results in a functional installation
2. set the path to the curl binaries
Now the question is, does R need the curl binary to be > 7.28.0 or only the libraries?
