At least on your system, Apache 2.2 seems to have changed its value 
for SCRIPT_NAME, which is what PmWiki has been using for deducing 
the path info data.  (A lot of configurations have traditionally 
provided incorrect PATH_INFO variables, which is why PmWiki went 
to an alternate detection mechanism based on the SCRIPT_NAME
and REQUEST_URI variables.)

So, because SCRIPT_NAME no longer works the way it did in
earlier versions of Apache, it's not getting the correct

I think the quick fix is to put 

    $pagename = ResolvePageName($_SERVER['PATH_INFO']);

at the top of your config.php.  

Longer-term, I'll have to figure out how to get PmWiki to 
properly detect the pagenames in yet-another-Apache-configuration
possibility.  :-(  :-(
