What you're doing here is using symbolic references. Symbolic references are a very bad idea and they should only be used very rarely.
They are such a bad idea that if you're programming with "use strict" turned on (and you should _always_ program with "use strict" turned on) then Perl turns symbolic references into compile time errors.
You very rarely have to use symbolic references (the only example I can think of is to alter the symbol table). You'll be far better off changing your code to use a hash instead.
my %vars;
my $variable1 = 'variable2';
$vars{$variable1} = 'Actual value';
print $vars{$variable1};
