It says:

   Note also that some versions of "flock" cannot lock things over
   the network; you would need to use the more system-specific
   "fcntl" for that.  If you like you can force Perl to ignore
   your system's flock(2) function, and so provide its own
   fcntl(2)-based emulation, by passing the switch "-Ud_flock" to
   the Configure program when you configure perl.

Perhaps that's the simplest workaround: either don't use NFS, or if
you do use it, build Perl with -Ud_flock.

Another possibility is to modify the Perl script to use the
system-specific flock, but that would require Perl portability
expertise that I don't have.
