Looks like Leopard perl executable does have perl probes but they are
different from the once listed in
http://blogs.sun.com/alanbur/entry/dtrace_and_perl
Here is what I did.
On one terminal ran perl and on another ran
$ ps -ef | grep perl
501 4385 4373 0 0:00.01 ttys000 0:00.01 perl
$ sudo dtrace -l -n perl4385:::
ID PROVIDER MODULE FUNCTION
NAME
18659 perl4385 libperl.dylib Perl_pp_sort
entry
18660 perl4385 libperl.dylib Perl_pp_dbstate
entry
18661 perl4385 libperl.dylib Perl_pp_entersub

18662 perl4385 libperl.dylib Perl_pp_last
exit
18663 perl4385 libperl.dylib Perl_pp_return
exit
18664 perl4385 libperl.dylib Perl_dounwind
exit
18665 perl4385 libperl.dylib Perl_pp_leavesublv
exit
18666 perl4385 libperl.dylib Perl_pp_leavesub
exit
Alan's blog talks about sub-entry and sub-return probes which do not
exist in Leopards version of the probes.
May be the apple folks can clarify.
