Yes, there have been *many* improvements to cmake between 2.6.4 and current.
This is very much worth it.

The question is how current we go.

* 2.8.8, which some distros may already have ( I think openSUSE 12.2 has =

2.8.8)
* 2.8.9 ...less likely that it's already in some distro
* 2.8.10 definitely not available in any distro when we'll require it
