[mod_python] Breaking things after upgrading MySQLdb (to 1.2.2)

Thanks,

but I still won't know what would have caused this.
I'm not running PHP (& never installed modules for it)
I don't have any other Apache modules that I know of that could be  
using MySQLdb.

After I restarted my machine, it first gave:

[Thu Jun 07 10:05:54 2007] [error] [client ::1] ExtractionError:  
Can't extract file(s) to egg cache\n\nThe following error occurred  
while trying to extract file(s) to the Python egg\ncache:\n\n  [Errno  
13] Permission denied: '/var/empty/.python-eggs'\n\nThe Python egg  
cache directory is currently set to:\n\n  /var/empty/.python-eggs\n 
\nPerhaps your account does not have write access to this directory?   
You can\nchange the cache directory by setting the PYTHON_EGG_CACHE  
environment\nvariable to point to an accessible directory.\n

(the full log details follow below)

Then I stop & started Apache, and the error was (again):

[Thu Jun 07 10:06:14 2007] [error] [client ::1] ImportError:  
Inappropriate file type for dynamic loading

So I decided that maybe MySQLdb 1.2.2 is too new for me, and I  
installed MySQLdb 1.2.1_p2
However, I am afraid that MySQLdb 1.2.2. is still there:
Python 2.4.1 (#2, Mar 31 2005, 00:05:10)
[GCC 3.3 20030304 (Apple Computer, Inc. build 1666)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
 >>> import MySQLdb
 >>> MySQLdb.version_info
(1, 2, 2, 'final', 0)

How could I revert safely to MySQLdb 1.2.1_p2 ?
Or what would I need to rebuild to get things working again? Apache?  
python?
