removing/re-installing gcc on MacOSX ?

[Sabine Kraml <sabine.kraml@xxxxxxx>]

Hello,

I am sorry for the stupid question, but as a newcomer to MacOSX I've
managed to screw up my gcc installation (there is a mismatch between
diferent library versions). What's the best way to remove all of gcc  
including
all libraries and reinstall it from scratch?

Thanks for your help,
Sabine
