It is still optional, amavisd 2.7.* or 2.8.0 will
start normally without Mail::DKIM, unless you require
their use by either $enable_dkim_verification=1 or
$enable_dkim_signing=1. Both of these settings are
off by default, so it must be a Gentoo default config
which is enabling one or the other.

Btw, $enable_dkim_verification and $enable_dkim_signing
are enabled in a *sample* config file that comes with
amavis. Not to be confused with their *default* value
(in absence of a config file). Perhaps this explains.
