Because it doesn't export anything. A program cannot modify the
environment of its parent, so gpg-agent has to be executed like this:

» eval $(gpg-aget --daemon)

» echo $GPG_AGENT_INFO
/tmp/gpg-dbASrL/S.gpg-agent:1762:1

The 'eval $(foo)' part is tells your shell (bash, zsh) to interpret
gpg-agent's output as commands; without it, all gpg-agent can do is
print them to stdout.
