With use strict you must delare vars once.

Code:
#!/usr/bin/perl -w
use strict;
use warnings;

#Clears Screen
my $CLEAR=`clear`;
print $CLEAR;

or

Code:
#!/usr/bin/perl -w
use strict;
use warnings;
#declare all vars you will use in the script first.
my $CLEAR;

#Clears Screen
$CLEAR=`clear`;
print $CLEAR;
