Can I assume you are trying to run the above as a job submitted to 
HTCondor?  If so, does it work when you run HistFitter outside of 
HTCondor?  Is yes, perhaps your HTCondor job submit file needs to 
specify the environment variables required (like ROOTSYS, etc)... I 
would suggest trying putting
   getenv = True
in your submit file and see if that helps. Also, perhaps you need a 
PYTHONPATH environment...  It may help if you posted your HTCondor 
submit file to the email list.

Another thought:  how does the worker node have access to the ROOT 
module?  It either needs to be installed on the worker node, or 
accessible via a shared file system (NFS, etc), or you will need to tell 
HTCondor which files to transfer...

Hope the above helps
