Possible error in NumericalMinimization.C tutorial

[Wile_E_Coyote]

Using the new Minimizer class on ROOT 5

Check if your ROOT has “minuit2” enabled: root-config --features If not, you will need to rebuild your ROOT 5 from scratch. Try to run the macro version which comes with your ROOT: ${ROOTSYS}/tutorials/fit/NumericalMinimization.C

Randomly a segmentation fault for uninitialized TTree

The “minimizer’s name” is case sensitive (i.e., you must use “Minuit2”). @Axel If “root-config --has-minuit2” returns “yes” but “Minuit2” is not working, then I think it is a bug (specific to the default ROOT installation on lxplus?). BTW. The default minimizer (when the “minimizer’s name” is empty) is the old “Minuit”.
