The official cadaver debian package doesn’t support ssl, because of some annoying licensing issues with openSSL. Therefore I recompiled the sarge version of cadaver with ssl enabled. After a bit of reading this turned out to be a quite simple process:

• apt-get source cadaver
• modify debian/rules: make the --without-ssl switch in the call to configure read --with-ssl, and change the package name to cadaver-ssl.
• modify debian/control: change package name again, add the line Conflicts: cadaver to indicate that only the original cadaver or our ssl version can be installed at the same time.
• build the deb using fakeroot dpkg-buildpackage

You can get the result here, or via apt-get install cadaver-ssl by adding the line

deb http://debian.jkraemer.net/apt sarge main contrib non-free

to your /etc/apt/sources.list.
