You've enabled gpg for both the target and native opkg recipes and there
is no gpg-native for opkg-native to work. If you only the target
verison, you could try:

PACKAGECONFIG_append_class-target = " gpg"

otherwise you need to enable a native version of gpgme, probably adding
BBCLASSEXTEND = "native" to the recipe for starters, there may then be
other tweaks needed.

Cheers,
