It would also be good to verify that you don't have multiple version of 
babeltrace installed.  For example, an older version installed by the 
package manager in /usr and a hand-compiled one in /usr/local.  
Executing the binary from /usr/local/bin/babeltrace could somehow load 
the shared library from /usr/lib, or vice-versa.
