You probably need the corresponding -dev package for libffi for your
distro in order to be able to compile Alien. Once that is installed,
run that command again and it should compile it (provided you have the
usual build tools installed). Let me know if you experience
compilation errors; in the past the Alien rockspec has been tricky to
compile in some systems.

Hope that helps,
