Hi, Apparently the current version has problems compiling with gcc 4.0 (http://www.zope.org/Collectors/Zope3-dev/366). This is the default on the new Mac OS X, I think, and occasionally Twisted users will have issues building there. Thanks! -- Itamar Shtull-Trauring <itamar at itamarst.org> http://itamarst.org
