Following the advice of Michael given below earlier in the list,
I was able to get Magic working fine on my PowerBook G4. 
I wanted to let the list know, as I had some serious
problems getting it to work before... A special note here
is that it would not work (correctly/fully) under OS 10.2,
but after I installed "Panther" everything compiles and works
fine.

Thanks for all of your help.
