[Halld-offline] [Halld-physics] Updating software for gcc 4.9.2

[Paul Mattione]

Also, if you are working on the ifarm, before setting up your environment, you can run:

module load gcc_4.9.2

Which will prepend the necessary locations for the gcc libraries and binaries.  Then just source your latest environment that is built with gcc 4.9.2.
