[X-Unix] How to get working directory in a perl script?

[Jerry Krinock]

Apparently, a perl script has a different "working" directory than the  
bash shell that spawned it, or something like that...

##### Script: ##########################

#!/usr/bin/perl

print "1. pwd is:         $ENV{'PWD'}\n" ;
my $newDir = "/Users/jk/Music" ;
if (chdir $newDir) {
     print "Succeeded chdir to $newDir\n" ;
}
my $wdContents = `ls` ;
print "wd contents:\n$wdContents\n" ;
print "2. pwd is:         $ENV{'PWD'}\n" ;

##### Actual Output: ##################

1. pwd is:         /Users/jk
Succeeded chdir to /Users/jk/Music
wd contents:
GarageBand
iTunes

2. pwd is:         /Users/jk

######################################

As you can see, the script did successfully change my working  
directory to /Users/jk/Music, but $ENV{'PWD'} is giving me /Users/jk.   
How can I get the correct answer?

Thanks,
