gpg-agent is older than us

[Ajax]

On a Debian box, 'gpg -K' gives "server 'gpg-agent' is older than us
(2.2.12 < 2.2.21)".   2.2.21 was built using speedo in my home
directory populating ~/bin which appears at the head of $PATH.  The
commands 'which gpg' and 'which gpg-agent' both point to ~/bin.
2.2.12 would have been installed by the Debian package manager with
/usr/bin/gpg-agent.  How can I cause '~/bin/gpg -K' to use
'~/bin/gp-agent' and omit "older than us" warning?

Thank You
