Yes, true.  There's a nice explanation of why it's a bad idea here:

OK.  To be honest I'm not too sure about how these aspects of UNIX work.
 Would this mean that only I can use the shared library, and that I can
only access it from within the bash shell?  Are there any more general
means for telling the system, "Look in /usr/local/lib as well as /usr/lib"?
