Thanks for that! I'll try it tommorow when I have a G4.

One other question.. I did "apt-get install gcc-3.2" and
it can't find the package. I took a look, and it seems that even though 
the packages are present on my mirror, they are not mentioned in the 
"Packages" file. Anyone know why this might be the case?

Thanks,
