I am a Debian maintainer of eigen3.
eigen3-3.0.4 was successfully built on all available platforms .
Moreover 3.1.0~alpha is in "experimental" branch  and it seems no
problems there as well.
But you should have "unstable" (sid) or "testing"(Wheezy) version of
Debian to have it.
There is a small issue with doc generation (required a patch , the
bug will be filed), but buildtests are passing
on all main platforms almost without problems.
