/tmp IS writeable (I even made it 777).
If safe mode or open_basedir are enabled, that usually won't help you one bit. Install 1.4beta6, which doesn't rely on writing a temporary compiled template file.
(The proxy key thing is completely unrelated and you may ignore it, it's harmless.)

Thanks a lot. Safe_Mode was off, but Open_BaseDir was defined. I will try 1.4 beta 6
Thanks again,
