That part got accidentally mangled when I asked my mailer to reflow the
message. It was supposed to be:

I'm at a loss, frankly. I don't understand. You're using GnuPG v2.1.11,
you can use the key itself, but the agent isn't aware of having it! That
does not compute. I can only think of one thing. Are you really using
GnuPG v2.1.11, or do you have GnuPG 1.4 co-installed and are you using
that? If the latter, that's not going to work with keygrips. If the name
of the binary you're invoking is "gpg", what does
"gpg --version" say?

Could you show the invocation and output of using gpg to sign or decrypt
something? Please add "-v" to the command line to make it more verbose.
And could you show command and output for determining the keygrip you're
intending to use?
