package samba4 4.0.0~alpha15~git20110124.dfsg1-2ubuntu1 failed to install/upgrade: subprocess installed post-installation script returned error exit status 1

[Lee Fisher]

I've been reading for a week.
 I just upgraded to Natty from Lucid because it was said certain bugs were fixed in alpha 15 regarding install. (and Lucid & Mavericks default install is Alpha14) I've been getting module errors, I have gone through and deleted my bin & lib directories in "/usr/local/samba/" directories. I have tried reinstalling this via git & apt-get. I hate the idea of giving devs more bs troubleshooting for something you prolly already know about, cause I'd rather have you coding. The recent traceback is:
Traceback (most recent call last):
  File "/usr/share/samba/setup/upgradeprovision", line 37, in <module>
    import samba
  File "/usr/lib/python2.7/dist-packages/samba/__init__.py", line 45, in <module>

ImportError: /usr/lib/i386-linux-gnu/libpytalloc-util.so.2: version `PYTALLOC_UTIL_2.0.5' not found (required by /usr/lib/samba/libsamba_python.so

I have tried:
alpha8 - Lucid's default before I populated the ppa repository.
git method - via http://wiki.samba.org/index.php/Samba4/HOWTO#Samba4_HOWTO
apt-get method via http://blog.mycroes.nl/2010/09/installing-samba-4-on-ubuntu-maverick.html

I have python-talloc 2.0.7 installed.

This is definitely fixed in newer versions, though I'm not entirely sure what the latest version with the fixes is.
