General :: Compile Cyanogenmod Gingerbread With Ubuntu 12.04

I'm trying to compile cm7 from source under ubuntu 12.04.

I compiled successfully on ubuntu 10.04 before, but my notebook got broken So on my new notebook I installed 12.04 (64bit).

Repo remained the same.I tried to setup build enviroment as described here.Had to additionally install packages schedtool ,zlib1g-dev and pngcrush.Now in the end of the compile process I get the following error:

Code:

frameworks/base/core/java/com/google/android/mms/pdu/PduPersister.java:23: cannot find symbol
symbol : class PduCache
location: package com.google.android.mms.util
import com.google.android.mms.util.PduCache;

Googled for it, but didn't find anything useful.
