How can Perl based daemons recover gracefully from momentarily unavailable NFS sources?

I have Perl scripts (running as daemons) on a large group of servers, where some Perl modules are used from an NFS mount.

Sometimes, these mounts are temporarily unavailable, and if at the exact moment the Perl module is accessed, the result is that the script/daemon dies.

Is there a way to change the Perl scripts globally – to recover gracefully from these NFS ‘hickups’, without surrounding each and every stanza that accesses the NFS-sourced Perl modules — with a try-except block?
