If you are going to tar and use SCP to copy a project from an OSX computer to a Linux based Wakanda server make sure you remove all the resource fork files from the expanded tar folder or do not include resource forks in the tar file. If you do not then the Wakanda server on the Linux box will not load since it will see the resource files as additional Wakanda project files and try to open them.
COPYFILE_DISABLE=1 tar -czf myProject.gz myProject/You can tell tar on the OSX computer to do this by placing COPYFILE_DISABLE=1 prior to the tar command. This will stop tar from including resources in the project and messing up the Linux server.
If you don't do this then you will have to clean all the ._ files from the project, or it will fail to start.
