Do you mean 10.3.3 and Geant 4.5.2, or really Geant4.2?

Because of the several dependancies, some packages are very long to 
build, but ...

... this is the likely suspect.
On a 400 MHz G4, my advice would be to have a LONG break ;-)
Geant 4 generally takes hours to compile on my 800 MHz TiBook, and Gate 
takes 1 hour...

... on the other hand, Geant4 build takes roughly one hour on my G5, 
whereas Gate only takes 10 min or so...

I installed Gate on my laptop, just to make sure this is feasible, but 
for any serious computation, you'll need the G5.

keep in touch - and welcome on Gate Users list,
