I believe in this case Xen 3.2.2 (or Xen 3.4) Hypervisor and tools have been built on Solaris Nevada (build 124 or higher) . e2fsprogs-devel should be RH's library (Linux).
I would guess, a kind of port of this library to SNV_124 ( or higher ) is required.

On Fedora 11/12 if xen is built with e2fsprogs-devel installed, pygrub
supports ext4.

If xen is built _without_ e2fsprogs-devel installed, then there's only ext3
support in pygrub.
