That really shouldn't be necessary for locally built applications since
these already know where the libraries are installed.  In fact doing it
this way opens a potential security hole since now the dynamic loader
trusts libraries in /usr/local/lib/ and may prefer it over system
libraries for _all_ applications (you may or may not want this
behaviour, but in any case should be aware of it).

Better set up the correct runtime search path with an '-rpath=<dir>'
argument to the linker invocation for the install and you never need to
invoke ldconfig.  Anything installed in /usr/local shouldn't require
full administrator privileges and certainly not alter the system
behaviour.  That most Linux distributions don't make that distinction
between system and local applications anymore doesn't mean it's the
correct thing to do...
