Given the current DEPENDS: ========================== REQUIRED_USE="static? ( !plugins !pkcs11 ) lzo? ( !lz4 ) pkcs11? ( ssl ) mbedtls? ( ssl !libressl ) pkcs11? ( ssl ) !plugins?

( dev-util/cmocka )" ===================== Nothing appears to pull in dev-libs/lzo with lzo support given the following USE flags: net-misc/openvpn-2.4_rc1::gentoo-overlay USE="lzo pam plugins ssl -down-root -examples -inotify -iproute2 -libressl -lz4 -mbedtls -pkcs11 (-polarssl) (-selinux) -static -systemd {-test}" *NOTE: gentoo-overlay is simply the latest anongit pulldown emerge of dev-libs/lzo followed by net-misc/openvpn-2.4_rc1 allows for the emerge to continue successfully.
Fixed in net-misc/openvpn-2.4_rc1-r1
