In the source location, cd ext/openssl and then ruby extconf.rb. This will generate a makefile in the ext/openssl directory. Simply make && sudo make install it to build the ruby openssl extension, and install the .so into the appropriate location.

and the same for ext/readline for readline support.

Then you should be able to make ruby properly.

cd ext/openssl
ruby extconf.rb
make && sudo make install

cd ext/readline
ruby extconf.rb
make && sudo make install

sudo make install
