Just did a fresh install of the tracker development branch and it looks like geant4 isn't installing correctly. I noticed that the third party bash script is looking for geant4.9.6_build.tar.gz (or something similar to that) when what downloads is a geant4.9.6.p02.tar.gz. I've changed this and ran the build_all.bash script (with all the other installs commented out, and after sourcing env.sh). This did not work, see below for the error it created:

INFO: Found source archive in 'source' directory
INFO: Source archive exists.
