[Zope] Missing pyexpat.so in Zope 2.6 binary for linux

Hi! When I have a PageTemplate with a non-standard content type (text/vnd.wap.wml) I get an error: -- 8< -- Site Error An error was encountered while publishing this resource. Error Type: ImportError Error Value: cannot import name expat -- 8< -- It works on the Windows version but on linux (Zope-2.6.0-linux2-x86.tgz) I had to copy the file pyexpat.so from another Python2.1 installation. Is there a better way to do it? (Would compile my own solve this?) And where should I report the bug? / Johan Lübcke
