Planner-list planner configure script bug

[Sebastien Roy <Sebastien Roy Sun COM>]

The planner configure script (in 0.14.2) looks for the libpython library 
by doing a find in "/".  On a system with hundreds of nfs mounted 
directories which may be extremely large, this approach is utterly 
broken, and takes forever.  Is this really necessary?  Why not just look 
for it in /usr/lib, and if it's not there, bail out.  The user could then 
be given the option of specifying a path on the configure command-line if 
it's not in /usr/lib.
