at Regina we have two versions:
gcc (GCC) 4.4.7 20120313 (Red Hat 4.4.7-11)
gcc (GCC) 4.4.7 20120313 (Red Hat 4.4.7-16)

The latest versions of Geant4 and ROOT6 now require GCC 4.8 or later. However, many of the Linux distributions we are now using, including those on the JLab farm, use GCC 4.4 by default. In particular RedHat 6 (at least as installed at JLab) uses 4.4.7. (The computer center has a 4.8 version available in /apps should we need it, but it is not the default.)
