Default System Gallery App doesn't compile

I'm trying to make a mobile mashup of existing apps

Got Default Android System Camera App for 2.2 Froyo from
android.git.kernel.org Git - platform/packages/apps/Camera.git/summary Works and compiles great

Got Default Android System GALLERY App for 2.2 Froyo from
android.git.kernel.org Git - platform/packages/apps/Gallery.git/summary

Doesn't compile! Some errors -
local variables mLength, mHeight ... cannot be resolved
import android.provider.DrmStore;... cannot be resolved

How can I compile and run the default gallery app on Froyo?
