[Zope] Zope and Python on FreeBSD 5.1

Hello again, I read on the net that there have been issues with Zope/Plone and Python on FreeBSD. Does anybody know what the status is today? Our production server is running FreeBSD 5.1 and Python 2.1.3. Zope itself seems to be stable, but some products are behaving strangely (on the other hand they behaved strangely on RedHat Linux too). -Petter-
