The find_xxx() calls try to load the value from the cache. If it's not there they try to find the stuff. If it's in the case but it contains "NOTFOUND" they search again. This way if something wasn't found and you install the lib it searches the next time again and will find it. Alex -- GMX DSL-Flatrate 0,- Euro* - Überall, wo DSL verfügbar ist!
