[Newbies] Chronos package loading error

Hi -

Chronos (http://www.chronos-st.org & http://www.squeaksource.com/Chronos 
) would load into and work in Squeak 3.9, but it won't load into 4.2. 
The error given is 'Futures must be sent messages'  I think this comes 
up because Chronos has a class InfiniteTimepoint that has two class side 

InfiniteTimepoint class >> polarity: polarity
	^polarity ifTrue: [self future] ifFalse: [self past]


InfiniteTimepoint class >> future
	Future == nil
			[Future :=
				(self basicNew)

For some reason when polarity: is compiled it is using Object>>future 
rather than the version of future that is defined by InfiniteTimepoint.

Is there any way to change the load/compile order of those two methods 
when loading into 4.2?  I know I could rename the InfiniteTimepoint 
version of future to something else but its a package that works as is 
on VisualWorks, Dolphin, Pharo, and Gemstone.  So I'd either maintain a 
separate version for squeak or have to get the package maintainer to 
make a change for all platforms and users.

I'm using linux and the all-in-one app from squeak.org

Thanks for any guidance you can provide.
