This seems to work fine on my Mac OS X (10.3 Panther) box, my linux 2.4 x86 box, and my linux x86_64 (amd64 opteron) box. Let me know if there are any problems (and fixes) so I can encorporate the fixes and reroll in a few days. My goal is to churn out updated -rc tarballs every few days until we get one that we like, at which point we'll call it 2.1.0 GA.
2.2.0 GA?
Regarding known problems in 2.1-dev which are regressions w.r.t. the stable branch, there are a couple of problems documented in stable branch STATUS that were caught before the changes were merged. (I can't get to that file right now.)
