The loaders come with the script and for most installs you don't need to do anything since they are set to load at runtime. However, on some installations a line needs to be installed in the php.ini file. Your host, if they are good with support, shouldn't have a problem adding this line for you.

There are some hosting options that allow the user to have their own php.ini file, but I just don't have the experience with these scenarios since my has always loaded at runtime.
