Well, I don't remember installing 8.5 (though the absence of memory is  
not necessarily a memory of absence in my case). It doesn't look to be  
an Active States installation and I'm sure that I didn't compile 8.5  
aqua. So I'm not sure where it came from if it didn't come with some  
system update.

Where do I look for this?
