CentOS 7:

I tried solutions in this post

sudo yum -y install libcurl libcurl-devel
sudo yum -y install openssl-devel

but wasn't enough.

Checking R error in Console gave me the anwser. In my case it was lacking libxml-2.0 below (and Console printed an explanation with package name to different Linux versions and other possible R configs)

sudo yum -y install libxml2-devel
