To be clear, did you install this version of perl, or did you rent access to a server where it was allready installed? Is this version of perl the default that gets run if you just type perl at a command prompt, or does it only get run if you set your environment or suchlike in a special way.

Unless you asked specificaly for it, if the datacenter admins installed an unstable version of perl as the default on a system they are renting to you then I would be very worried about their competency. Perhaps they also forgot to setup the backups correctly, or to put fuel in backup generator. (As happend recently at the Co-lo facility that my company uses).

If you are running anything important on this server, I would start looking for an alternative hosting provider. Even if there is nothing important, I would only continue to use them if they are very cheap, and I had comprehensive backups.
