Ah, terribly sorry, yes, some distros don't include that path.
Others do. And they /should/.

Assuming that is done, when you build and install software the
  installer usually is supposed to automatically run ldconfig
  which automatically switches over to the newly installed libraries.

To go back to the packaged version you MUST uninstall your
  built version.

Correct, that would happen if /usr/local was NOT in ldconfig's
  search path.
That's why it really should be in the path if users are to build
  their own software.
