NPE while inflating ActionBarSherlock on old Andro

I am using ActionBarSherlock and have the dreaded problem:

I don't have any style in the manifest as my app takes Theme.Sherlock directly. My ABS version is the last 4.4.0 and I am trying to run my app in an API 11 emulator (API 8 leads to the same result). API 18 works fine.

After a little debugging in Eclipse, it looks that the following returns both null views (ActionBarView.java):

@Override
protected void onFinishInflate() {
    mUpView = findViewById(R.id.abs__up);
    mIconView = (ImageView) findViewById(R.id.abs__home);
}

and of course the subsequent calls are returning the NPE. It also looks like I have some warning in my LogCat:

01-08 22:54:20.093: I/dalvikvm(626): Could not find method com.actionbarsherlock.internal.nineoldandroids.widget.NineFrameLayout.onHoverEvent, referenced from method com.actionbarsherlock.internal.widget.ActionBarContainer.onHoverEvent

What can be my problem?

PS.: I use Eclipse + Maven and include both android-v4 support 19.0.1 and NineOldAndroids 2.4.0.

EDIT

After some other debugging it looks like the generated resource numbers in ActionBarSherlock and R.txt (target/ folder generated by Maven) are not the same. Checking in the debugger, I have:

R.txt -> int layout abs__action_bar_home 0x7f030000 | Debug -> same
R.txt -> int id abs__up 0x7f07000b | Debug -> ox7f04000b
R.txt -> int id abs__home 0x7f07000a | Debug -> 0x7f04000a

UPDATE

It looks like there is a problem while importing apklibs...something goes wrong with the R compilation. The workaround is to remove the the custom resources that misalign the ids of abs__* ones and mess up the numbering. For instance I did the following:

I checked where ActionBarSherlock was failing, for me it was while loading the resource R.id.abs__up.
I have got the resource number from my R.java file and note it down (0x7f07XXXX);
I removed all the resources before 0x7f07XXXX, cleaned the project, regenerated R. I wanted to align back R.id.abs__up to its apklib number (0x7f04000b). I had to remove three folders (anim/, xml/ , raw/) and three actual resources from my string xml.
Now R.id.abs__up had the correct number in my compiled R.java.
