Note: cjdns-postinst-pkg file (with --genconf) is OK

However, all other exit codes of 127 are attempting to call function default_postinst

root@OpenWrt:~# cat /usr/lib/opkg/info/cjdns.postinst
#!/bin/sh
[ "${IPKG_NO_SCRIPT}" = "1" ] && exit 0
. ${IPKG_INSTROOT}/lib/functions.sh
default_postinst $0 $@

Ah. The only postinst directive is cjdns/Makefile -- the call to default_postinst is a feature in openwrt/trunk /lib/functions.sh. Works in meshbox/for-14.07
