See "man gprof" for details.  Basicly, the libraries contain code which 
is instrumented so that you can figure out things like where the program 
is spending CPU time and what the call graph looks like.  These are used 
by developers for performance tuning only, and are not needed for 
production systems which are not running test/debug code...
