I hadn't thought of that last trick- good one.

I was really tired so I guess I wasn't thinking too straight, but the 
fact that the logs were showing no such file for say 
/twiki/bin/configure was really only making me think of the configure 
script file- not that it couldn't find the interpreter- so my attention 
was focused on that. The fact perl was on a slight different path was 
not really registering at the time at all. Very misleading for the tired 
and weary... :)

I had considered running the test server in exactly the same form as the 
production, but that was going to be my very last resort and after a 
very long sleep!

Moral of the story: Don't try diagnostics when you're so tired that you 
can't see straight, let alone think straight. You'll miss the small 
details that can make a huge difference ;)
