解决办法

I use System.getProperty("user.home") to get a home dir. You can change this by: 
java -Duser.home=some/dir -jar apktool.jar d some.apk
Everything about sources and building them is written in the wiki: http://code.google.com/p/android-apktool/wiki/BuildApktool .
You can change framework dir path in: apktool-lib/src/main/java/brut/androlib/res/AndrolibResources.java#getFrameworkDir().
