Re-link After Make Install

The magical command sudo /sbin/ldconfig -v reconfigures/indexes the files you installed into the lib.

For example, if you see errors such as:

~/w/h/build (master) [127]> curse
curse: error while loading shared libraries: libhexer.so.1.1.0: cannot open shared object file: No such file or directory

Or similiarly

~/w/e/build (master)> entwine
entwine: error while loading shared libraries: libentwine.so.2: cannot open shared object file: No such file or directory

Then go and run the magical command.

Typically this is needed when you do sudo make install after compiling some C++ code. I suppose you don't need the -v verbose flag, because ldconfig - configure dynamic linker run-time bindings.
