[gate-users] Gate simulation crashing on TBranch constructor

[Stephen Adler]

To answer my own question, I think I figured out the problem. During the 
configuration stage
of building geant4, I set G4ANALYSIS_USE to the default value of "n". I 
then reconfigured geant4 and set this value to "y" since after reading 
the text of the installation procedure carefully, realized that this was 
probably the method by which geant4 got its data out to the world. In 
anycase, I've got Gate now
running on my Fedora Core 3 setup.

Cheers. Steve.
