I get:

koen at dominion:/OE/tentacle/build$ touch ../sources/openembedded-core/meta/recipes-graphics/xorg-lib/libxrender_0.9.6.bb 
koen at dominion:/OE/tentacle/build$ bitbake libxrender-native -DDD | grep append
DEBUG: Appending .bbappend file /OE/tentacle/sources/meta-openembedded/meta-oe/recipes-graphics/xorg-lib/libxrender_0.9.6.bbappend to /OE/tentacle/sources/openembedded-core/meta/recipes-graphics/xorg-lib/libxrender_0.9.6.bb
DEBUG: BB /OE/tentacle/sources/meta-openembedded/meta-oe/recipes-graphics/xorg-lib/libxrender_0.9.6.bbappend: handle(data, include)
DEBUG: LOAD /OE/tentacle/sources/meta-openembedded/meta-oe/recipes-graphics/xorg-lib/libxrender_0.9.6.bbappend

It then chokes on renderproto-native, which gets fixes by touching the .bb. So it looks like bitbake has some caching issues.

I have that already :)
