Answer 1

On Ubuntu, you need to install libssl-dev in order to install the header files for SSL.:

sudo apt-get install libssl-dev

or via Synaptic.

It's probably a good idea to also install libcurl4-openssl-dev, which last I checked you needed for the related package RCurl.

Answer 2

I have the same problem, but for RHEL. I have sudo yum install openssl-devel and problem solved!
