Piergiorgio,
Don't worry about the warnings when creating the shared library.
This is always the case under ALPHA/Unix with both cxx and gcc
when one creates a shared library with references to external
symbols.

When you run groot, you must have set the LD_LIBRARY_PATH before.
For example
 setenv LD_LIBRARY_PATH $ROOTSYS/lib
