Nothing wrong with macosx -- it behaves like any other unix system as far as perl is concerned. So maybe if you show us more information... What is the command line you use to run the script? You showed us three lines of code... Is that all there is to the script?

Here are some examples of shell commands that execute the three lines of perl code you showed us, and these all work for me, using command lines in a Terminal shell window (or in an xterm shell) -- I'm showing the shell prompt ("bash$ ") so that you can see which lines are command-line inputs that I typed; the lines that don't start with "bash$ " are the command outputs. 

bash$ perl -e 'print "What is your name? "; $name = <STDIN>; print "Yo
+ur name is $name\n"'
What is your name? Me
Your name is Me


bash$ cat test.perl
#!/usr/bin/perl
print "What is your name? ";
$name = <STDIN>;
print "Your name is $name\n";

bash$ chmod +x test.perl

bash$ test.perl
What is your name?  You
Your name is you

So, what are you doing that is different from those examples?
