[Jlab-scicomp-briefs] ROOT PRO link updated

[Robert Michaels]

On the ifarm CentOS 6.2 systems, the production link for ROOT has
been updated today

    /apps/root/PRO -> 5.34.13

This may cause small disruptions (users need to recompile ?).

Note, one may also use an older version, e.g. "use root/5.34.01"
which was the previous PRO version.
