I updated the current stable ebuild to work with 3.2.2b (and the recently updated apache2). Not sure if I did so properly, but it's working good for me :) Reproducible: Always Steps to Reproduce: 1. 2. 3.
I'd rather not add a betaversion to the tree unless there's some compelling reason to do so other than it being never :) People who want to use the beta version can easily add their own ebuild to a portage overlay - copying the 3.1.4-r1 ebuild should work fine.
