I'm confused by it all, too. At any rate, the math portions are no 
longer found (even when fixing the IlmImf->OpenEXR thing), and that has 
to be fixed.

 From all I've read on the internet, one thing seems quite obvious: 
Those math portions are no longer part of an accompanying library, but a 
library that - at least at this point - constitutes an entirely 
independent project. And I've found talk about it having been "renamed" 
(whatever that means) from `IlmBase` to `Imath`.


It's an ideal job to be delegated: I'm just as confuzzled by it all as 
anyone else.
