Stupid Rez Hang and its fix

In Xcode the build of my little AudioUnit project hang at the Rez step. The Rez step ? Yeah, MacOS 9 is alive and well in the CoreAudio/QuickTime parts of Mac OS X. You define little four character constants, that are rezzed into your component, because - I don't know - plists are too cumbersome ?

Anyway for unfathomable reasons Rez didn't want to compile my resource file anymore. It entered a death loop of lseek and read and never returned.

^C
 And then there it just hangs This has happened before exactly the same way and in a similiar way to others , but there was no good solution for my problem in those mail threads.

The way I "fixed" it , was to run the command with sudo. Yeah that's voodoo, but it worked.
