FWIW libtool runs ldconfig when installing the libraries, but does so
wrongly. It only works if you've installed the libraries in that place
before.

If it is the first time you are installing the libraries, you need to
manually run ldconfig.
I think this is because it uses ldconfig -n, which doesn't rebuild the
cache.

IMHO safest is to just run ldconfig with no params, zlib is doing just
that, so it is fine.
