Well I have run into a strange problem using Linux. I've prepared a directory on my Server to hold .mcz files. So far so good. Now with Pharo 1.3 this files are properly loaded and save. with 1.4 I got errors about readStream that is nil or an bitOr: missing in Character. Someone wrote the .mcz file must be served as zip files. If I'm running file on an .mcz file this is properly recogniced: WebContfakt-FriedrichDominicus.76.mcz: Zip archive data, at least v2.0 to extract but apache seems to serve this files as text. I checked the first few bytes of the .mcz files and found: PK\C\D that is PK\3\4 I modified the magic file for apache to cope with it: 0 string PK\003\004 application/x-zip But still I run into trouble. So does anyone know how to properly configure Apache 2 that this files are properly served? Thanks Friedrich
