Hi Belen,
It looks like you are mixing two versions of gcc: you seem be
using 2.95 but your ROOT lib path points to 2.96 .
You should check your environment variable LD_LIBRARY_PATH and
make sure that you have the following path
/afs/cern.ch/sw/root/v3.05.05/rh73_gcc2952/root/lib
in there (instead of /afs/cern.ch/sw/root/v3.05.05/rh73_gcc296/root/lib).
Cheers,
Gerri
ps: you may find detailed instructions about setting LD_LIBRARY_PATH
at http://root.cern.ch/root/Install.html
