Yes:

KDE 4.1 does not need eigen2 (only eigen1). However, something just occured to 
me: KOffice trunk uses eigen2 and wants to build against KDE 4.1 (for that 
reason I was asked to backport FindEigen2.cmake to the 4.1 branch). So it is 
probably more convenient if you can leave eigen2 in.

Indeed, Eigen1 should be gone by the time KDE 4.2 is released. We are 
currently working on porting all existing Eigen1-based code throughout KDE 
and its dependencies. Already /trunk/koffice, Avogadro (for Kalzium) and 
KGLLib are ported.

Quoting James Richard Tyrer:
>Package: eigen-2.0-alpha7  Only an Alpha; doesn't sound good.

With 3 projects already ported to it, it is quickly maturing; we will release 
a beta shortly and the final version later this autumn (definitely in 2008).

Cheers,
Benoit
