Hi, The PEAR package Horde_Dav contains file coming from Sabre_VObject with the same path. As a consequence, those two packages are not co-installable [1]. I'm wondering: why is is not a dependency instead? [1]: See http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=710593, no idea how it behaves using pear only. Regards -- Mathieu Parent
