I'd say make the changes now, as people who have been keeping up to date from 
kdesupport would presumably already have eigen installed.

People installing eigen for the first time should use the 2.0.3 release even 
if it's not packaged by the distro yet, no?  It would be more convenient for 
people using build scripts to convert 2.0.3 over but I think that's more work 
than necessary (and besides, just prolongs the inevitable at this point).

Of course others may have different thoughts. :)
