I've manually installed (download and install locally): Selenium Standalone Server 3.40 IE Driver Server 3.4 (32 bit) childprocess 0.7.1
When I try to install ffi 1.9.10 manually I get the following gem_make.out error. Internet security is pretty tight so I am unable to gem install filename.gem. I have to do the local install. Thanks
