This would only be true if the Babeltrace libraries are removed from
/usr/local/lib afterwards, but keeping /usr/local/bin/babeltrace,
because as far as I know, unless the distribution's package somehow
removes it, the executable is built with an explicit RPATH to locate its
own libraries, and this is the first place libraries are searched for.

Hence having multiple installations of Babeltrace is usually not a
problem, unless you mess with the file system manually.
