Hi Developers I right installed caldavd on a relatively conservative debian system.. Additional dependencies where (debian sarge): libkrb5-dev, python-xattr, curl, libsqlite3-dev, python-pyopenssl I suggest you to build something like a target to fix dependencies automatically based on OS or simply provide such an informal dependency list inside the tree... I read about people trying to install it under "unstable" environment, but the dependencies seem to be conservative to run it in a (ulterior) unchanged stable environment. The version we're talking of is calendarserver 20061207 trunk: For xattr i'm not understanding why they replaced deadPropertyXattrPrefix with "user." instead of "user.WebDAV" but that's another maintainer... right? The originally posted bug #47 here also suggested that. The only compiling error was due to the PyKerberos includes with missing prefix "gssapi/" as already fixed in your repository. Thanks a lot for this great product! Hope all these clients around in the Linux&Windows world get soon adult... -- Miro Dietiker
