Tiger + WO5.2.4 update and wo adaptor not getting requests

I have just updated a server from from Panther to Tiger and upgraded WO 
from 5.2.2 to 5.2.4

I now can't get through to my WO apps via apache. The apps are running and 
I can connect to JavaMonitor and my apps via direct connect.

When trying to access via apache I get:

The requested URL /cgi-bin/WebObjects/MyApp.woa... was not found on this 
server.

If I touch /tmp/logWebObjects I do not see any WebObjects.log created so I 
think it is clear that WebObjects isn't getting to process the requests at 
all. What I am not sure is whether it has started up ok.

My httpd.conf does include the line:

Include /System/Library/WebObjects/Adaptors/Apache/apache.conf

Apache (v 1.3.33) has no complaints when it starts up though I don't see 
any startup logging within /tmp/WebObjects.log - that file just isn't 
created - I've noticed it isn't written out on a working server either 
until the first WO app request comes in.

wotaskd is running ok but I don't think I'm getting that far.

Help!
