From the docs for PPerl: 
$ pperl <perl params> -- <pperl params> scriptname <script params>

I think you need this: 

#!/usr/bin/perl -- --prefork 25
print "\n\nHELLO\n";

You need to tell pperl that your perl options are through and your pperl options have started. The '--' by itself should do that.

Update:

I got PPerl to install (had to play some ndbm/gdbm games with the makefile, though), and tested this theory. You do need the separator between the perl options and the pperl options, even if you have no perl options to name. The pperl arguments seem to work with either the equal sign or a space.

Update 2: You're right, and I did run it accidentally as perl instead of pperl on the sheband line. When I try, I get the same thing you do. Yet /usr/local/bin/pperl --prefork=25 foo works from the command line, with a Perl program in file "foo". Perhaps PPerl just doesn't support working from the shebang line, and must be invoked on a program that's in a file.
