* ldconfig  on install; move reinstall remove

Run ldconfig after package installs so apps don't complain about missing just installed libraries. Also, do reinstalls as part of the upgrade path so that package remove happens after the package to be reinstalled has been downloaded. This fixes upgrades on curl (or its dependencies) erroring out on being unable to download the new package using curl.
