I don't understand the question. The writer should only die if there is no
reader, not if the pipe is full (it should just block at that point). Since
your script is the reader, I don't see why the writer should have any
problem.

IO::Handle should run under 5.005.
But you can just open the fifo with a regular open():
open(FIFO, 'mypipe') or die $!;
while(<FIFO>) {
print;
}
