Module usage :Global symbol "$ref" requires explicit package name


Hi,

I have package Filesys:f installed and visible through
/usr/local/bin/perldoc Filesys:f.
It has supported functions df();

When I write a simple program to use the function:

#!/usr/local/bin/perl -w
use Filesys:f;
use strict;
use POSIX;

$ref = df("/tmp");
print "\/tmp $ref->{used}";

It gives an error
Global symbol "$ref" requires explicit package name at ./test.pl at line 6
Global symbol "$ref" requires explicit package name at ./test.pl at line 7

Kindly help.

Regards,
Rajat Garg
