Proguard con libreria sherlock

[Alemanarg]

Hola!!

Recientemente he leido mucho sobre el uso de proguard, utilizandolo en otro momento.
Pero ahora, con la librería sherlock estoy teniendo problemas.
En principio, luego de actualizar el ADT y el proguard, me salen unos errores y ante esto, me gustaría chequear mi configuración ante todo.

En el proguard.bat que me bajo lo modifiqué y quedó:
call %java_exe% -jar "%PROGUARD_HOME%"\lib\proguard.jar %*

En el project:
- Project properties:
target=android-14
proguard.config=proguard.cfg
android.library.reference.1=../ActionBarSherlock-4.2.0/librarySherlock

proguard.cfg:

-optimizationpasses 5
  -dontusemixedcaseclassnames

Alguien tiene esta configuración?

Muchas gracias!!!!
