Yep, the problem seemed to be that all the 3.2.3 stuff was in /usr/local 
thus overriding the 3.3.1 files which use just the /usr prefix.  Whether 
this was a failure of the 3.2.3 uninstall script or not I'm not sure, I 
had to remove all the old files manually (obviously uninstalling and 
reinstalling 3.3.1 wouldn't help, as this wasn't the problem).

Problem solved, anyway.
